Ngemva kweminyaka ecishe ibe ngu-10 yentuthuko, izimoto ezintsha zikagesi zamandla sezenze amadiphozithi athile obuchwepheshe.Ukwakhiwa kwezingxenye zemoto kagesi kanye nezingxenye kunolwazi oluningi, phakathi kokuklanywa kwei-precharge resistorkumjikelezo wangaphambi kokushaja udinga ukucabangela izimo eziningi nezimo zokusebenza.Ukukhethwa kwe-precharge resistor kunquma isivinini sesikhathi sokushajwa kwemoto ngaphambili, usayizi wesikhala esithathwe i-precharge resistor, ukuphepha kwemoto ephezulu kwamandla kagesi, ukwethembeka kanye nokuzinza.
I-Precharge resistoriyi-resistor eshaja kancane kancane i-capacitor ekuqaleni kwamandla kagesi wemoto, uma singekho isixhasi sangaphambi kokushajwa, umsinga wokushaja uzoba mkhulu kakhulu ukuthi ungaphula i-capacitor.Amandla aphezulu-voltage angezwe ngqo ku-capacitor, okulingana ne-short-circuit esheshayo, i-short-circuit current ngokweqile izolimaza izingxenye zikagesi eziphezulu.Ngakho-ke, lapho uklama isifunda, i-precharge resistor kufanele icatshangelwe ukuze kuqinisekiswe ukuphepha kwesifunda.
Kunezindawo ezimbili kumjikelezo we-high-voltage wemoto kagesi laphoi-precharge resistorkusetshenziswa, okuyisekhethi yokushajwa kwesilawuli semoto kanye nesesekeli yokushaja yangaphambi kokushaja enevoltheji ephezulu.Isilawuli se-motor (i-inverter circuit) sine-capacitor enkulu, edinga ukushajwa ngaphambili ukuze ulawule i-capacitor yokushaja yamanje.Izesekeli zamandla kagesi aphezulu zibuye zibe ne-DCDC (DC converter), i-OBC (ishaja esebhodini), i-PDU (ibhokisi lokusabalalisa lamandla kagesi aphezulu), iphampu yamafutha, iphampu yamanzi, i-AC (i-compressor air-conditioning) nezinye izingxenye, kuzoba khona. i-capacitance enkulu ngaphakathi kwezingxenye, ngakho-ke zidinga ukushajwa ngaphambili.
