I-Rectifier ityhila i-EV charging converter

Imodyuli yetshaja ye-RT22 EV inomlinganiselo we-50kW, kodwa ukuba umenzi ufuna ukwenza itshaja enamandla aphezulu angama-350kW, unokuqokelela nje iimodyuli ezisixhenxe ze-RT22.

Iiteknoloji zoLungiso

I-RT22 entsha ye-isolated power converter yeRectifier Technologies, yi-RT22, yimodyuli yokutshaja ye-50kW yesithuthi sombane (EV) enokubekwa ngokulula ukuze kwandiswe umthamo.

I-RT22 ikwanayo nolawulo lwamandla olusebenzayo olwakhelwe kuyo, olunciphisa impembelelo yegridi ngokubonelela ngendlela yokulawula amanqanaba ombane wegridi. I-converter ivulela abavelisi betshaja ithuba lokucwangcisa iHigh Power Charging (HPC) okanye ukutshaja ngokukhawuleza okufanelekileyo nakwiindawo zedolophu, njengoko imodyuli ihambelana neentlobo ngeentlobo zeeklasi ezimiselweyo.

I-converter inamandla angaphezu kwama-96% kwaye inoluhlu olubanzi lwe-voltage yokuphuma phakathi kwe-50VDC ukuya kwi-1000VDC. I-Rectifier ithi oku kwenza i-converter ikwazi ukujongana ne-voltage yebhetri yazo zonke ii-EV ezikhoyo ngoku, kuquka iibhasi zombane kunye nee-EV ezintsha zabakhweli.

“Sizinike ixesha lokuqonda iingxaki zabavelisi be-HPC kwaye sayila imveliso ejongana neengxaki ezininzi kangangoko,” utshilo uNicholas Yeoh, uMlawuli weNtengiso kwiRectifier Technologies, kwingxelo.

Impembelelo yegridi enciphileyo
Njengoko iinethiwekhi zokutshaja ze-DC ezinamandla aphezulu ezinobukhulu obufanayo namandla zisasazwa kwihlabathi liphela, iinethiwekhi zombane ziya kubekwa phantsi koxinzelelo olukhulayo njengoko zitsala amandla amakhulu nangenaxesha, nto leyo enokubangela ukuguquguquka kwe-voltage. Ukongeza koku, abaqhubi benethiwekhi bajongene nobunzima bokufaka ii-HPC ngaphandle kokuphucula inethiwekhi ngemali eninzi.

I-Rectifier ithi ulawulo lwamandla olusebenzayo lwe-RT22 lulungisa ezi ngxaki, lunciphisa iindleko zenethiwekhi kwaye lubonelela ngokuguquguquka okukhulu kwiindawo zokufakela.

Imfuno yokutshaja enamandla aphezulu eyonyukileyo
Imodyuli nganye yetshaja ye-RT22 EV inikwe umlinganiselo we-50kW, inkampani ithi inobungakanani obucwangcisiweyo ukuze ihlangabezane neendidi zamandla ezichaziweyo zeetshaja zeDC Electric Vehicle. Umzekelo, ukuba umenzi we-HPC ufuna ukwenza itshaja enamandla aphezulu angama-350kW, banokuqhagamshela nje iimodyuli ezisixhenxe ze-RT22 ngaxeshanye, ngaphakathi kwendawo yombane.

“Njengoko ukusetyenziswa kwezithuthi zombane kuqhubeka kusanda kwaye ubuchwepheshe bebhetri buphucuka, imfuno yee-HPC iya kunyuka ngenxa yoko njengoko zidlala indima ebalulekileyo ekuququzeleleni ukuhamba imigama emide,” utshilo uYeoh.

“Ezona HPC zinamandla kakhulu namhlanje zimalunga ne-350kW, kodwa amandla aphezulu ayaxoxwa kwaye ayacwangciswa ukulungiselela ukufakwa kombane kwizithuthi ezinzima, ezifana neelori zemithwalo.”

Ukuvula iingcango ze-HPC kwiindawo zasezidolophini
“Ngokuhambelana ne-Class B EMC, i-RT22 inokuqala kwisiseko esingxolo ephantsi kwaye ngaloo ndlela ifaneleke ngakumbi ukufakwa kwindawo yasezidolophini apho kufuneka kuthintelwe khona ukuphazamiseka kwe-electromagnetic (EMI),” wongeze watsho uYeoh.

Okwangoku, ii-HPC zihlala kwiindlela ezinkulu kuphela, kodwa i-Rectifier ikholelwa ukuba njengoko ukungena kwe-EV kukhula, kuya kuba njalo nesidingo see-HPC kwiindawo zasezidolophini.

“Nangona i-RT22 yodwa ingaqinisekisi ukuba i-HPC yonke iya kuthobela udidi B – njengoko kukho ezinye izinto ezininzi ezingaphaya kombane ezichaphazela i-EMC – kuyavakala ukuyinikezela kwinqanaba lokuguqula amandla kuqala,” utshilo uYeoh. “Ngesiguquli samandla esithobelayo, kunokwenzeka ngakumbi ukwenza itshaja ethobelayo.

"Ukusuka kwi-RT22, abavelisi be-HPC banezixhobo ezisisiseko ezifunekayo kubavelisi beetshaja ukuze bakwazi ukucwangcisa i-HPC efanelekileyo kwiindawo zasezidolophini."
