Lub tsheb dav dav yog ib qho ntawm feem ntau loj tshaj plaws rau cov khoom siv hluav taws xob. Hnub noEv cov chargersCov qauv tsim muaj cov khoom siv hluav taws xob rhiab, suav nrog tswj hluav taws xob, kev siv hluav taws xob, kev pom zoo, roj teeb kev tswj hwm,Lub Tsheb Hluav Taws Xob Tsheb, thiab ntawm-board Chargers. Ntxiv rau cov cua sov, kev hloov hluav taws xob, thiab cov phiaj xwm hluav taws xob yuav tsum muaj kev tiv thaiv los ntawm AC kab kev ntxhov siab rau kev ua haujlwm txhim khu kev qha.
Niaj hnub no cov khoom siv sib xyaw muaj cov khoom siv ntau yam rau kev tiv thaiv hluav taws xob. Vim kev sib txuas rau daim phiaj, ntawm-Board Charger tiv thaiv los ntawm voltage s sundges siv cov khoom sib txawv yog qhov tseem ceeb.
Ib qho kev daws teeb meem tshwj xeeb ua ke ib qho kev sib txuas lus daws teeb meem thiab cov ntaus pob (SMD lossis tht), mus txog ib qho kev ntsuas hluav taws xob tsawg hauv qab cov mem tes high surge mem tes. Lub Sureloral + Mov Ua ke ua ke pab kev xaiv cov khoom siv tsheb txhim kho kom zoo thiab yog li ntawd, tus nqi ntawm lub zog sandiconductors hauv kev tsim. Cov ntu no xav tau los hloov AC Voltage rau hauv DC Voltage kom them lub tshebOn-Board Roj Teeb ThemCov.
Daim duab 1. Nyob rau-Board Charger Thaiv Thaiv
Lub ntawm-boardThem nyiaj(Ob lub) yog qhov pheej hmoo thaum lub sijhawmEv khoomVim tias raug cov txheej txheem overvoltage uas tej zaum yuav tshwm sim ntawm lub hwj chim sib koom. Tus qauv tsim yuav tsum tiv thaiv lub zog semiconductors los ntawm kev hloov pauv hloov pauv vim tias voltages siab dua lawv qhov kev txwv siab tshaj plaws tuaj yeem ua rau lawv puas. Txhawm rau txuas ntxiv ntawm EV kev ntseeg tau thiab lub neej, engineers yuav tsum daws cov kev tshaj tawm thiab qis dua close cov hluav taws xob hauv lawv cov qauv.
Piv txwv li cov khoom ntawm kev hloov chaw voltage muaj xws li cov hauv qab no:
Hloov ntawm lub peev xwm thauj khoom
Hloov ntawm cov hluav taws xob tsawg thiab resonant circuits
Cov kab luv luv ua rau kev tsim kho, kev sib tw tsheb khiav tsheb, lossis cua daj cua dub
Ua rau muaj kev tiv thaiv fuses thiab kev tiv thaiv kev tiv thaiv.
Daim duab 2. Pom zoo nrog Circuit Court rau cov sib txawv thiab ib hom kev hloov hluav taws xob hluav taws xob siv hluav taws xob siv cov chaw thiab GDT.
Ib qho 20 hli mov yog qhov zoo dua rau kev ntseeg tau zoo dua thiab tiv thaiv. Lub 20mm mov muab 45 lub pulses ntawm 6kv / 3ka Surge tam sim no, uas muaj ntau zog ntau dua li 14mm mov. Lub 14mm disc tsuas tuaj yeem tsuas yog siv ib ncig 14 surges dhau nws lub neej.
Daim duab 3. Clamping kev ua haujlwm ntawm LNFuse v14338J38555555555555555555555555uto Lub closeCing voltage tshaj 1000000.
Piv Txwv Piv Txwv
Qib 1 Charger-120Vac, ib leeg-theem Circuit: Qhov kev cia siab huab cua kub yog 100 ° C.
Kom paub ntau ntxiv txog kev siv cov sawb lossis tiv thaiv thyristors hauvhluav taws xob tsheb, Rub tawm qhov yuav ua li cas los xaiv qhov kev tiv thaiv kev hloov pauv hloov tshiab rau EV ntawm pawg neeg foob, kev ua siab zoo ntawm me me fuse, Inc.
