Nyuma yimyaka hafi 10 yiterambere, ibinyabiziga bishya byamashanyarazi byashizeho uburyo bwo gukusanya ikoranabuhanga. Hariho ubumenyi bwinshi mugushushanya ibice byimodoka yamashanyarazi no guhitamo no guhuza ibice. Muri byo, igishushanyo mbonera cya precharge irwanya umuzenguruko ukenera gusuzuma ibintu byinshi hamwe nakazi keza. Guhitamo ibiyobora preharge bigena umuvuduko wigihe cyimodoka, ubunini bwumwanya ufitwe naKurwanya, n'umutekano, kwiringirwa, no gutuza kw'amashanyarazi afite ingufu nyinshi.
Imashini ibanziriza iyambere ni résistoriste yishyuza buhoro buhoro capacitor mucyiciro cya mbere cyumuriro mwinshi wumuriro wikinyabiziga. Niba ntamwanya uhari, amashanyarazi arenze urugero azasenya capacitor. Umuyagankuba mwinshi ukoreshwa muburyo butaziguye kuri capacitor, bingana numuzunguruko mugufi. Umuyoboro mugufi cyane uzangiza ibice byamashanyarazi yumuriro mwinshi.Niyo mpamvu, résistor ya precharge igomba kwitabwaho mugihe hateguwe umuzenguruko kugirango umutekano wumuzunguruko.
Hano hari ahantu habiriabarwanyazikoreshwa mumashanyarazi aringaniye kandi yumuriro mwinshi wibinyabiziga byamashanyarazi, aribyo moteri igenzura moteri ya moteri yumuzunguruko hamwe n’umuzunguruko mwinshi wa voltage. Hano hari capacitor nini mugenzuzi wa moteri (umuzenguruko wa inverter), ukeneye kubanziriza kugenzura ubushobozi bwumuriro. Ibikoresho bikoresha ingufu nyinshi muri rusange harimo DCDC (DC ihindura DC), OBC (charger yo mu ndege), PDU (agasanduku ko gukwirakwiza amashanyarazi menshi), pompe yamavuta, pompe yamazi, AC (compressor de airing) nibindi bikoresho, kandi hariho na ubushobozi bunini imbere yibigize. , bityo rero kwishyurwa birasabwa.
Kurwanya abarwanyaR. Kubwibyo, kwishyurwa birashobora kurangira vuba kandi ntibizahindura ingamba zo kugenzura ibinyabiziga. Ibisabwa kugirango harebwe niba preharging yarangiye ni ukugera kuri 90% ya voltage yumuriro wa batiri (mubisanzwe niko bimeze). Mugihe uhisemo prezarge irwanya ibintu, hagomba gutekerezwa ibintu bikurikira: ingufu za batiri yumuriro, umuhuza wapimwe numuyoboro, capacitor C agaciro, ubushyuhe ntarengwa bwibidukikije, izamuka ryubushyuhe bwumubyigano, voltage nyuma yo kwishyurwa, igihe cyo kwishyiriraho, agaciro kokwirinda, imbaraga za pulse. Imibare yo kubara ingufu za pulse ni kimwe cya kabiri cyibicuruzwa bya kare ya voltage ya pulse na point capacitance C agaciro. Niba ari impyisi ikomeza, noneho imbaraga zose zigomba kuba igiteranyo cyingufu za pulses zose.
