Tom qab ze li ntawm 15 xyoo ntawm txoj kev loj hlob, lub zog tshiab hluav taws xob tsheb tau tsim qee qhov kev tso nyiaj. Kev xaiv ntawmpre-charge resistortxiav txim siab qhov ceev ntawm lub tsheb pre-them lub sij hawm, qhov luaj li cas ntawm qhov chaw nyob los ntawm lub pre-them tsis kam, lub tsheb lub high-voltage hluav taws xob kev nyab xeeb, kev cia siab thiab stability.
Pre-charge kuj yog nyob rau hauv lub tsheb high-voltage hwj chim ntawm lub capacitor thaum pib qeebcharging resistor, yog tias tsis muaj tus nqi them ua ntej, qhov them tam sim no yuav loj dhau los ua txhaum lub capacitor. High-voltage fais fab ntxiv ncaj qha mus rau lub capacitor, sib npaug rau ib qho luv luv tam sim no, dhau qhov luv luv tam sim no yuav ua rau cov hluav taws xob muaj hluav taws xob puas. Yog li ntawd, thaum tsim lub Circuit Court, lub pre-them tiv thaiv yuav tsum tau coj mus rau hauv tus account kom ntseeg tau tias kev ruaj ntseg ntawm lub Circuit Court.
Muaj ob qhov chaw nyob rau hauv high-voltage circuit ntawm lub tsheb hluav taws xob qhov twgpre-charge resistoryog siv, uas yog lub cev muaj zog controller pre-charge circuit thiab high-voltage accessory pre-charge circuit. Lub cev muaj zog maub los (inverter Circuit Court) muaj lub capacitor loj, uas yuav tsum tau them ua ntej los tswj lub capacitor them tam sim no.
Raws li qhov tseeb tsim pov thawj pom: ceramic resistor yog cov tswv yim ntau dua precharge, tawm thiab lwm yam yuav tsum tau ua. Nws muaj lub peev xwm tshwj xeeb kub thiab tuaj yeem nqus tau lub zog siab thaum lub sijhawm them ua ntej hauv lub sijhawm luv luv.
