Te Whanaketanga Hangarau Tino Pai o te Nekenekehanga Noho: He aha te haumi ki ngā utunga kāinga Wallbox DC e karo ai i ngā here OBC, e whakahohe ana i te kaha V2H/V2G, ā, e whakanui ana i te whai huatanga o te pūngao mā te hangarau SiC mō te oranga pumau ā muri ake nei

Whakarāpopototanga

Kei te uru te whakawhiti ā-ao ki te nekenekehanga hiko ki tētahi wāhanga tuarua, he wāhanga matatau ake. Ahakoa i arotahi te tekau tau tuatahi ki te tango waka me ngā hanganga tūmatanui, ko te tekau tau o nāianei e tautuhia ana e te arotautanga o te pūnaha utu kāinga. Kei te ngākau o tēnei whanaketanga ko te Wallbox DC Home Charger. I ngā wā o mua, ko te utu kāinga te rohe o ngā teihana Taumata 2 o te Auaha Rerekē (AC), e whakawhirinaki ana ki te On-Board Charger (OBC) ā-roto o te waka. Heoi, ko ngā herenga hangarau o te OBC—e whakatauhia ana e te taumaha, te rahinga, me te utu—kua hanga he arai mō te whakatupuranga e whai ake nei o ngā kāinga motuhake ki te hiko.

Kei roto i tēnei tuhinga he ruku hohonu, e 6,000 kupu te roa, ki te hiranga hangarau, hikohiko, me te ōhanga o ngā pouaka pakitara DC. Ka tūhuratia e mātou te āhua o te karo a ēnei taputapu i te OBC hei tuku utu tere ake, whai hua ake; me pēhea te whakamahi i ngā haurua-ā-hiko Silicon Carbide (SiC) hei whakaiti i ngā ngaronga wera; me te take he turanga nui rātou mō ngā tono Waka-ki-te-Kāinga (V2H) me te Waka-ki-te-Whatunga (V2G). Hei tāpiri, ka tātarihia e mātou te whakaurunga o ngā rihi DC ki roto i ngā Pūnaha Whakahaere Pūngao Kāinga (HEMS), tō rātou tūranga i roto i te waitohu whare noho papai, me te huarahi utu-painga mō te wā roa i te mea he tauine whakaputa.

Upoko 1: Te Huringa Tauira i roto i te Whakamahinga EV Kāinga – Mai i te AC Utility ki te DC Intelligence

Ko te hītori o te utu waka hiko (EV) he mea whakararuraru. I ngā rā tōmua o te ao EV hou, ko te whāinga matua he whakarite kia taea te whakakī anō i te waka i te pō mā te whakamahi i ngā hanganga hiko o ngā whare noho. Nā tēnei i ārahi te mana o te utu AC. I roto i te whakatakotoranga AC, ko te pouaka pakitara he pana haumaru whakakororia (he EVSE - Electric Vehicle Supply Equipment) e tuku tika ana i te mana AC ki te waka. Ko te mahi taumaha - te huri i taua mana AC ki te mana DC e hiahiatia ana e te pākahiko - ka mahia e te On-Board Charger (OBC) o te waka.

Ahakoa he iti te utu o te tāutanga o te utu hiko AC, he iti noa iho. I te tipu haere o te kaha o te pākahiko mai i te 60kWh ki te 100kWh me tua atu, ka noho te wā e hiahiatia ana hei utu i te 7kW, 11kW rānei AC hei arai whakahaere mō ngā whare e whakamahi nui ana. Ko te mea nui ake, ka whakaarohia e te tauira AC te EV hei kawenga kore mahi—he "totoka" mō te pūngao.

Whakauruhia te Wallbox DC Home Charger. Mā te neke i te tukanga whakawhiti AC-ki-DC i waho o te waka ki roto i tētahi waeine pakitara motuhake, ka huakina e mātou tētahi taha hou o te mahi. Ko tēnei nekehanga he whakawhiti mai i te "AC Utility" ki te "DC Intelligence." Ehara te DC wallbox i te rihi noa; he pokapū hikohiko mana matatau. Ka kōrero tika ki te Pūnaha Whakahaere Pūhiko (BMS), ka whakarato i te mana whakahaere ngaohiko me te iahiko tika e karo ana i ngā herenga o roto o te waka.

Ka tirohia e tēnei upoko ngā au-rahi e ārahi ana i tēnei panonitanga:

1. Te Whai i te Tere:Kei te tautokohia e ngā waka hiko teitei ngā hoahoa 800V. Kāore e taea e ngā rihi hiko AC te whakamahi i ēnei tere i te kāinga. Ahakoa he iti ake te mana o ngā pouaka hiko DC (hei tauira, 20kW ki te 30kW), he whakapai ake nui atu i ngā waeine hiko 7kW paerewa.
2. Mana Motuhake o te Pūngao:Ko te pikinga ake o te rokiroki pūngao rā me te pākahiko kāinga ka hanga he "rauropi DC." Ko te huri i te hiko rā DC ki te AC mō te whare, kātahi ka hoki ki te DC mō te motuka, he maha ngā ngaronga huringa. Ko te taiao kāinga e honoa ana ki te DC, me te pouaka pakitara DC hei pūtake, ka whakaiti i ēnei "taake huringa."
3. Te Matapihi Maamaa:I te neke haere o ngā ratonga hiko ki ngā kaupapa utu e pā ana ki te wā whakamahi me te urupare ki te tono, mā te mana whakahaere whānui e tukuna ana e ngā pūnaha DC ka taea e ngā kaipupuri whare te whai wāhi atu ki te whakatau i te whatunga hiko kia pai ake te whai hua atu i ngā tatūnga AC tuku iho.

Upoko 2: Te Rerekētanga Hangarau – Te Karo i te Ārai i te Pūnaha Utauta i Runga i te Papa (OBC)

Hei mārama he aha te take he mea hou te utu hiko DC ki te kāinga, me mārama tuatahi ki te "OBC Bottleneck." Kei roto i ia EV kua utua ki te AC he Charger On-Board. He kaitahuri hiko tēnei wāhanga e tango ana i te 120V, 240V AC rānei, ka whakatika ki te ngaohiko DC o te pākahiko.

Heoi, he patunga te OBC i te ahupūngao o te motuka. Nā te mea me haere tahi me te waka, he tino herenga kei raro i a ia:

• Taumaha me te Rōrahi:Ko ia kirokaramu o te OBC he kirokaramu taumaha e whakaiti ana i te whānuitanga o te waka. Nō reira, ko te nuinga o ngā kaihanga ka whakawhāiti i te OBC ki te 7kW, ki te 11kW rānei hei penapena wāhi me te taumaha.
• Whakahaere Wera:He nui te wera ka puta mai i te hurihanga o te 11kW o te mana. Me whakakore tēnei wera e te porowhita whakamatao o te waka, ka pau ai te pūngao tāpiri.
• Utu:He nui te utu hanga i ngā OBC kaha-tiketike (hei tauira, 22kW), ā, he maha ngā wā ka tukuna ki ngā tauira papai, ki ngā whakapainga kōwhiringa rānei.

Ina whakamahia e koe he Wallbox DC Home Charger, ka karohia katoatia te OBC. Ka hono tika te DC wallbox ki te pākahiko o te waka mā roto i ngā pine DC o te hononga CCS, NACS rānei. He maha ngā pānga nui o tēnei:

2.1 Te Kīanga Mana Teitei Ake me te Kore Taumaha Waka

Mā te whakatakoto i ngā taputapu whakawhiti ki te pakitara o te karāti, kāore ngā kaihangarau e herea ana e ngā taumaha o te waka. Ka taea e tātou te whakamahi i ngā inductors nui ake, ngā pūnga kaha ake, me ngā pūnaha whakamatao pai ake. Mā tēnei ka taea te utu i ngā whare noho ki te 15kW, 20kW, tae atu ki te 25kW—ngā tere kāore e taea te whakauru ki roto i te waka tonu, ā-tinana, ā-ōhanga hoki.

2.2 Ngā Hua Whai Hua

Ko te whai huatanga o tētahi OBC kei waenganui i te 85% ki te 92%. He nui te ngaronga "haere-hoki" ina whakaarohia ngā mano tini o ngā huringa utu i roto i te tekau tau. Ka taea e ngā pouaka pakitara DC, e whakamahi ana i ngā wāhanga ahumahi me te whakamatao motuhake, te whakatutuki i te whai huatanga neke atu i te 96%. Mā te karo i te whakatikatika ā-roto o te motuka, ka haere tika te pūngao mai i te whatunga hiko (te rā rānei) ki te rokiroki matū o te pākahiko me te iti o te para.

2.3 Te Pono me te Āheitanga ki te Ratonga

Ki te pakaru te OBC, ka mau te waka, ā, me whakatikatika nui, uaua hoki i tētahi kaihokohoko hiko. Ki te pakaru te pouaka pakitara DC, ka taea tonu te utu i te waka i tētahi teihana tūmatanui, mā tētahi rihi kawe AC tārua rānei, ā, ka taea te mahi tiaki, te whakakapi rānei i te pouaka pakitara tonu e tētahi tohunga hiko me te kore e pā ki ngā wāhanga o roto o te waka.

Upoko 3: Ngā Painga Hikohiko – Te Arotau i te Roa o te Pūhiko me te Whai Hua

Ko tētahi whakaaro hē noa ko te "he kino te utunga DC mō ngā pākahiko." Ahakoa ka taea e te utunga DC tūmatanui tino tere (350kW+) te whakaputa i te ahotea wera,Te utunga DC kāinga(i waenga i te 10kW ki te 25kW) he "wāhi reka" hikohiko e tuku ana i ētahi painga ki te utu AC.

3.1 Te Whakarerekētanga Whānui Pāpā (PWM) me te Whakahaere Rikiriki Tika

Ko te tukanga hurihanga AC-ki-DC i roto i te OBC o te waka ka puta he "aukati ripple" - he iti noa ngā piki me ngā heke o te putanga DC ka taea te whakawera i roto i ngā pūtau pākahiko. Ka whakamahia e ngā pouaka pakitara DC teitei ngā tukatuka tohu mamati matatau (DSP) hei whakarato i tētahi tohu DC "ma ake". Ka whakaitihia e tēnei pumau ngā ngaronga ātete ā-roto i roto i ngā pūtau Li-ion i te wā o te tukanga utu.

3.2 Ngā Āwhio Utu Hihiri

Ina utu ana mā te AC, me tono te BMS o te motuka i te hiko mai i te OBC, ka tangohia mai i te pakitara. Ka taea e tēnei whakawhitiwhitinga maha-taahiraa te whakaroa. Ka kōrero tahi te pouaka pakitara DC me te BMS mā te kawa ISO 15118. Mā tēnei ka taea he ānau utu hihiri ake, ā, ka aro atu. Mena ka kitea e te BMS he pikinga paku o te pāmahana i roto i tētahi waeine pūtau motuhake, ka taea e te pouaka pakitara DC te whakarerekē tonu i te rere o te iahiko, he tino tika ake i tā te OBC.

3.3 Te Whakaiti i te "Wera Tahuri"

I te wā e utu ana te hiko AC, ka tukuna te wera e puta mai ana i te OBC ki te pākahiko nā te mea he rite tonu te ara iahiko whakamatao e whakamahia ana, ā, he tata tonu hoki. Ka taea e tēnei kawenga wera tuarua te whakatere i te pirau o te electrolyte. Mā te neke i te tukanga hurihanga whakaputa wera ki te pouaka pakitara, ka noho mātao tonu te pākahiko o te waka i te wā e whakamahia ana, ka tiakina te hauora o te paparanga SEI (Solid Electrolyte Interphase) i runga i te anode.

Hei whakarāpopototanga, ko te utu hiko DC kāinga ka whakarato i te tere o te utu tere me te "ngawari" o te utu puhoi, me te pupuri tonu i te pumau hikohiko matū pai mō te roa o te ora o te pākahiko.

Upoko 4: Hangarau Silicon Carbide (SiC) – Te Ngākau o te Huringa Tino Pai

Ko te wāhanga ngaro e taea ai te whakamahi i ngā pouaka pakitara DC hou mō te kāinga ko te whakawhiti mai i ngā MOSFET me ngā IGBT Silicon (Si) tuku iho ki ngā semiconductors Silicon Carbide (SiC). He rauemi whānui-bandgap (WBG) te SiC kua tino whakarerekē i te āhua o ngā hikohiko mana.

4.1 Ngā Āhuatanga Pai o te Āputa Pae

E toru ngā wā te whānui ake o te āputa o te Silicon Carbide i tērā o te silicon tuku iho. Mā tēnei ka taea e ngā taputapu SiC te mahi i ngā ngaohiko me ngā pāmahana teitei ake. I roto i te pouaka pakitara DC, ko te tikanga ka taea e te waeine te whakahaere i ngā whakaritenga 400V, 800V rānei o ngā pākahiko EV hou me te iti noa o te tapuwae wāhanga.

4.2 Te Whakaiti i ngā Ngaronga Whakawhiti

Ko te painga nui o te SiC i roto i te rihi kāinga ko te whakaiti i ngā ngaronga whakawhiti. Ka ngaro te kaha o ngā pana silicon tuku iho i ia wā ka tahuri, ka whakaweto hoki, nā te puhoi o ō rātou wā urupare me te kaha teitei ake. Ka taea e ngā pana SiC te mahi i ngā auau teitei ake (he maha ngā wā he 10x teitei ake i te silicon). Mā tēnei whakawhiti auau teitei ka taea te:

• Ngā Aukume Iti Ake:Nā te mea he teitei ake te auau whakawhiti, ka iti ake, ka mama ake hoki ngā inductors me ngā transformers i roto i te pouaka pakitara. Koinei te mea e taea ai e te rihi DC 20kW te iti hei whakairi ki te pakitara o te karāti, kaua ki te kāpata pouaka whakamātao.
• Teitei ake o te Whai Hua:Ka whakaitihia e te SiC te ngaronga pūngao tae atu ki te 80% ki te whakatauritea ki te huringa e ahu mai ana i te silicon. Mō te kaipupuri whare, ka iti ake ngā pire hiko me te wera para.

4.3 Te Whakahaere Wera me te Pono

Nā te mea he pai ake te mahi a te SiC, he iti ake te wera e whakaputaina ana. Ko te tikanga o te iti o te wera, kāore pea te pouaka pakitara e hiahia ki ngā pā hauhautanga haruru, tiaki nui. He maha ngā pouaka pakitara DC e hangai ana ki te SiC ka taea te whakamahi i te whakamatao wai kore mahi, i ngā hoahoa totohu wera matatau rānei. Ka whakanui ake tēnei i te roa o te ora o ngā hikohiko, nā te mea ko te huringa wera te tino take o te rahunga o ngā wāhanga i roto i ngā pūnaha hiko.

4.4 Tātaritanga Whakataurite: Si me te SiC i roto i ngā Taupānga Whare Noho

Hei tino maioha ki te SiC, me titiro ki ngā whakapainga tau. I roto i te kaitahuri 20kW noa:

• Te Whakaiti i te Tapuwae:Tērā pea ka hiahiatia he āputa 15-rita mō tētahi pūnaha e ahu mai ana i te silicon hei pupuri i ngā pā whakamatao me ngā inductors nui. Ka taea e tētahi pūnaha e ahu mai ana i te SiC te uru ki roto i tētahi āputa 4-rita, he whakaiti i te rōrahi mā te 73%.
• Auautanga Whakawhiti:Ko te tikanga, ko ngā IGBT Silicon he iti noa iho te oro ki te 20kHz ki te 30kHz nā runga i ngā herenga wera. Ka mahi pai ngā MOSFET SiC i te 100kHz ki te 300kHz. Ehara tēnei i te inenga hangarau noa iho; e pā tika ana ki te taumaha o ngā takai parahi i roto i ngā whakawhiti hiko, e whai wāhi nui ana ki te pire rauemi (BOM).
• Te Whai Hua i te Utaina Wāhanga:Ko te nuinga o ngā rihi hiko kāinga ka mahi i te kawenga hapa (hei tauira, 5kW kaua ki te 20kW) mō te nuinga o tō rātou oranga. Ka mau tonu te pai o te SiC (94%+) ahakoa te kawenga 20%, engari ko te pai o te silicon ka heke tere ki te 80s iti, ki te 70s teitei rānei i ngā taumata mana iti.

4.5 Te Pānga o te Huringa Wera ki te Roanga Ora

Ka pāngia ngā taputapu utu hiko kāinga e ngā taiao kino—ngā whare karāti makariri i te takurua, ngā whare werawera i te raumati. He tino tairongo ngā haurua-ā-irahiko silicon ki ngā piki me ngā heke o te "pāmahana hononga". I ia wā ka tīmata te taputapu utu silicon, ka whānui, ka whakawhāiti ngā wāhanga o roto. I roto i ngā mano tini huringa, ka hua ake te ngenge o te tūhono me te pakaru o te hononga waea. Ko te whānui o te āputa o te SiC me te kawe wera teitei e tohu ana ka noho pumau tonu te pāmahana o roto, ka nui ake te pikinga o te MTBF (Mean Time Between Failures) o te taputapu mai i te toharite o te ahumahi 5 tau ki te neke atu i te 12 tau.

Upoko 5: Ngā Utauta DC Wallbox hei Kūaha ki te V2H (Waka-ki-te-Kāinga) me te V2G (Waka-ki-te-Whatunga)

Ko te take tino hira pea mō te haumi ki tētahi pouaka pakitara DC ko tōna tūranga hei whakahohe i te rere o te pūngao e rua ngā ahunga. Ahakoa kei reira ētahi pūnaha AC rua ngā ahunga, he herenga ā-roto ēnei e ngā taputapu o roto o te waka. Ko te utunga rua ngā ahunga DC te paerewa koura mō te manawanui ki te pūngao.

5.1 Te Waka hei Pūhiko Noho (V2H)

Ko te pākahiko EV hou e pupuri ana i waenga i te 60kWh me te 100kWh o te kaha. He nui tēnei hei whakakaha i tētahi whare mō ngā rā e toru ki te rima. Heoi, hei whakamahi i tēnei kaha hei whakakaha i tō whare i te wā e mate ana te hiko, me whai huarahi koe ki te tango i te hiko DC mai i te pākahiko ka huri ki te AC mō ngā ara iahiko o tō whare. Ko te pouaka pakitara DC te mea hei kuaha. Nā te mea ka karo i te OBC, ka taea e ia te tango tika i te hiko mai i te kete pākahiko, ka huri ki te 240V AC, ka whāngai ki te papa hiko o te whare (mā te pana whakawhiti). Mā tēnei ka huri te EV hei "Powerwall" nui, nekeneke, e whakarato ana i te kaha nui atu i te pākahiko kāinga tūmau motuhake i te utu iti iho.

5.2 Te Whakapūmautanga o te Whatunga me te Whiwhinga Moni (V2G)

Ka neke ake tēnei mahi mā te Waka-ki-Whatunga (V2G). I roto i te horopaki V2G, ka kōrero te pouaka pakitara DC ki te kaiwhakarato ratonga. I ngā wā e tino hiahiatia ana, ka taea e te whatunga te "nama" i te iti o te hiko mai i ngā mano tini o ngā EV e tū ana. Ko te tikanga ka utua te kaipupuri whare mō tēnei ratonga, ka whakaiti i te utu katoa o te mana. He pai ake ngā pouaka pakitara DC mō te V2G nā te mea he tere ake te urupare me te nui ake o te mana e tukuna ana. Mena me werohanga ohorere te whatunga o te 20kW hei ārai i te mate o te hiko, ka taea e te pouaka pakitara DC te whakarato tonu, engari ko te AC OBC paerewa ka herea pea ki te 7kW, ā, kāore pea e tautoko i te rere rua-aronga.

5.3 Ngā Whare Hiko Mariko (VPP)

Mā ngā rihi hiko DC ka taea e ngā kaipupuri whare te whakauru atu ki ngā Whare Hiko Mariko. Mā te whakakotahi i ngā rau o ngā whare e hono ana ki te DC, ka taea e te kaiwhakahaere VPP te tuku kaha nui ki te mākete hiko rarawe. Mā tēnei ka hangaia he "ōhanga hiko" hou mō te rāngai noho, ina he rawa hohe te EV, kaua ki te whakapaunga kore mahi.

5.4 Te Rautaki Tiaki "Te Āhua o te Mana" (SoC)

Ko tētahi o ngā āhuatanga matatau o ngā pūnaha DC V2G ko te kaha ki te whakahaere i te hauora o te pākahiko me te tautoko i te whatunga hiko. Kāore i rite ki ngā pūnaha AC e "patupatu" ana i te pākahiko me ngā huringa papaku, koretake, ka taea e te pouaka pakitara DC te mahi i te "whakakorenga tika". Ka taea e ia te tango i te nui o te kaha e tonoa ana e te whatunga hiko me te whakarite kia kaua te pākahiko e heke iho i te paepae kua tautuhia e te kaiwhakamahi (hei tauira, 20% SoC), ā, ka mahia e ia i te tere tukunga tino pai e whakaiti ana i te wera ā-roto.

Upoko 6: Te Whakaurunga Hōhonu ki ngā Pūnaha Whakahaere Pūngao Kāinga (HEMS) me ngā Pūngao Whakahou

Ehara te rihi hiko Wallbox DC i te taputapu takitahi; he pūnga nui i roto i te "Kāinga Atamai o te tau 2030." Ina whakauruhia ki te Pūnaha Whakahaere Pūngao Kāinga (HEMS), ka noho te pouaka hiko DC hei kaiwhakahaere matua mō te taurite pūngao o te whare.

6.1 Te Ariā "Pahi DC"

Kei te anga whakamua ngā whare e ātete ana ki te heke mai ki te hoahoa matua-DC. Ka whakaputahia e ngā panera rā te DC. Ka rongoa e ngā pākahiko kāinga te DC. Ka whakamahia e ngā EV te DC. I roto i te whare AC tuku iho, ka hurihia te pūngao ki mua, ki muri (DC -> AC -> DC -> AC), me te ngaronga 3-5% i ia taahiraa. Ka taea e te pouaka pakitara DC te hono tika. Ka taea te tuku tika i te mana DC i hangaia e te rā ki te pākahiko EV me te kore e haere i roto i te kaitahuri AC. Ko tēnei utunga rā "Direct-to-EV" te tihi o te whai huatanga, e whakarite ana kia whakamahia ia photon i hopukina e te tuanui mō te nekenekehanga.

6.2 Taurite Utaina Maamaa

Ka taea e te pūmanawa HEMS te whakamahi i te pouaka pakitara DC hei whakataurite i te kawenga katoa o te whare. Hei tauira, ki te tīmata te pūnaha HVAC, ā, ka tata ki te neke atu i te rohe tono nui o te whare, ka taea e te HEMS te whakawhāiti tonu i te pouaka pakitara DC mai i te 20kW ki te 10kW. Nā te mea ka whakahaerehia te utunga DC mā te mamati, ā, ka karo i ngā whakaroa o roto o te waka, ka puta ēnei whakatikatika i roto i ngā mirihekona, kia kore ai e pakaru te pakaru matua o te whare.

6.3 Tātari Matapae me te Whanoke a te Kaiwhakamahi

Ka taea e te HEMS Whakauru te tātari i ngā matapae huarere, ngā utu ratonga, me te maramataka a te kaiwhakamahi. Mena ka mōhio te pūnaha he roa te haerenga āpōpō, ā, ka whiti te rā i tēnei rā, ka whakaritea te utu hiko pūngao rā DC i te ahiahi. Mena ka kite i ngā utu ratonga teitei i te ahiahi, ka whakamahia e ia te pouaka pakitara DC hei tango i te hiko mai i te motuka hei whakahaere i te mīhini horoi rihi me ngā rama (V2H), kātahi ka whakakī anō i te motuka i te 3:00 AM i te wā e iti rawa ana ngā utu.

6.4 Ngā Pānga o te Rōpū Waka Whakakotahi i roto i ngā Wāhanga Whānau Maha

I roto i ngā whare noho, i ngā whare noho papai rānei, ka taea te hono i ngā pouaka pakitara DC ki te hanga i tētahi "whatunga moroiti." Engari ko ia whare noho he hononga whatunga motuhake e 90% te kore mahi, ka taea e tētahi pahi DC pokapū te tohatoha hiko i waenga i ngā motuka. Mena kua kī katoa tētahi motuka, ka tukuna tonutia tōna wāhanga o te kaha DC ki tētahi motuka kua tae mai. Ka taea anake tēnei "tohatoha kaha hihiri" me te whakawhitiwhiti tere me te whakahaere kei roto i ngā pūnaha DC.

Upoko 7: Hangarau Ā-tinana – Tāutanga, Arotautanga Wāhi, me te Whakahaere Wera

Ko te whakawhiti o te utu hiko DC mana-teitei mai i ngā whare putunga ahumahi ki ngā whare noho i hiahiatia he mahi toi hangarau ā-tinana. Ahakoa he rite te rahi o te utu hiko DC tūmatanui ki tētahi mīhini hoko nui, me kiato, kia ātaahua, kia marino hoki te pouaka pakitara DC noho. Hei whakatutuki i tēnei, me whai auahatanga i roto i ētahi wāhanga matua.

7.1 Te Āhuatanga o te Huringa Mana: Te Pūtahuri Āhuatanga

Hei whakatutuki i te kaha teitei, ka whakamahia e ngā pouaka pakitara DC kāinga ngā kaitahuri resonant LLC, ngā āhua Phase-Shifted Full Bridge (PSFB) rānei. Mā ēnei ara iahiko ka taea te "Switching Soft," ka tahuri, ka whakaweto hoki ngā semiconductors i te kore ngaohiko (ZVS) i te kore iahiko rānei (ZCS). Ka whakaitihia nuitia e tēnei te EMI (Electromagnetic Interference)—he mea nui mō ngā taiao kāinga kei reira ngā taputapu Wi-Fi tairongo me ngā taputapu kāinga atamai—ā, ka whakaitihia te rahi o ngā tātari ā-roto me ngā totohu wera.

7.2 Whakahaere Wera: Kei tua atu i te Pā

I roto i te whare noho, he āwangawanga nui te haruru. Kāore e whakaaetia he rihi 20kW me te hau ahumahi haruru mō te karāti e piri ana ki te rūma moe. He maha ngā rautaki kua whakamahia e ngā miihini hei whakahaere puku i te wera:

• Ngā Aukume Kua Kōpakihia:Ko ngā wāhanga pēnei i ngā inductors kua whakauruhia ki roto i ngā kapia kawe wera e kukume ana i te wera ki te anga o waho.
• Ngā Whakawhiti Wera Wai-ki-Hau:Ko ētahi pouaka pakitara DC papai e whakamahi ana i tētahi koropiko wai iti, puku (he rite ki tētahi PC petipeti) hei neke i te wera mai i ngā kōwae SiC ki tētahi anga konumohe nui-mata e mahi ana hei whakamahana kore mahi.
• Ngā Rauemi Huri-Āhua (PCM):Ka whakamahia e ngā waeine matatau ngā PCM hei mimiti i te wera i ngā wā poto, kaha-nui, ā, ka tukuna mārire i roto i te wā, ka taea ai te kaha teitei ake me te kore e whakamatao kaha.

7.3 Te Hanganga Tāutanga: Te Pūnaha "Wāwāhia"
