Xa kuxoxwa ngezinto ezintsha kunye nokuphuculwa kwenkqubo yokufakelwa kombane kwizithuthi zombane, ingqwalasela idla ngokubekwa kwiindawo eziphambili ezifana neyunithi yokulawula ephambili kunye nezixhobo zamandla, ngelixa iindawo ezincedisayo ezifana nee-capacitors zidla ngokungafumani ngqwalasela ingako. Nangona kunjalo, ezi ndawo zincedisayo zinempembelelo enkulu ekusebenzeni kwenkqubo iyonke. Eli nqaku liza kujonga ukusetyenziswa kwee-capacitors zefilimu ze-YMIN kwiitshaja ezikwibhodi kwaye lihlolisise ukukhethwa kunye nokusetyenziswa kwee-capacitors kwizithuthi zombane.

Phakathi kweentlobo ngeentlobo zee-capacitors,ii-capacitors ze-aluminium electrolyticzinembali ende kwaye zibambe isikhundla esibalulekileyo kwicandelo le-elektroniki yamandla. Nangona kunjalo, ngokuvela kweemfuno zobuchwepheshe, imida yee-capacitors ze-electrolytic iye yabonakala ngakumbi. Ngenxa yoko, kuye kwavela enye indlela engcono—ii-capacitors zefilimu.

Xa kuthelekiswa nee-capacitors ze-electrolytic, ii-capacitors zefilimu zibonelela ngeenzuzo ezibalulekileyo ngokubhekiselele ekunyamezeleni kwe-voltage, ukumelana nochungechunge olulinganayo oluphantsi (ESR), ukungaguquguquki kwe-polarity, ukuzinza okuqinileyo, kunye nobomi obude. Ezi mpawu zenza ii-capacitors zefilimu zibalaseleyo ekwenzeni lula uyilo lwenkqubo, ukuphucula amandla ombane we-ripple, kunye nokubonelela ngokusebenza okuthembekileyo phantsi kweemeko ezinzima zendalo.

Itheyibhile: Iingenelo zokuthelekisa ukusebenzaii-capacitors zefilimukunye nee-capacitors ze-aluminium electrolytic

Ngokuthelekisa ukusebenza kwee-capacitors zefilimu kunye nendawo yokusetyenziswa kwezithuthi zombane, kuyacaca ukuba kukho ukuhambelana okuphezulu phakathi kwezi zimbini. Ngenxa yoko, ii-capacitors zefilimu ngokungathandabuzekiyo zezona zinto zikhethwayo kwinkqubo yokufaka umbane kwizithuthi zombane. Nangona kunjalo, ukuqinisekisa ukuba zifanelekile kwizicelo zeemoto, ezi capacitors kufuneka zihlangabezane nemigangatho engqongqo yezithuthi, njenge-AEC-Q200, kwaye zibonise ukusebenza okuthembekileyo phantsi kweemeko ezinzima. Ngokusekelwe kwezi mfuno, ukukhethwa nokusetyenziswa kwee-capacitors kufuneka kuhambelane nale migaqo.

Inkqubo ye-OBC (On-Board Charger) idla ngokuba nezinto ezimbini eziphambili: isekethe yokulungisa eguqula amandla e-AC mains abe yi-DC, kunye ne-DC-DC power converter evelisa i-DC voltage efunekayo yokutshaja. Kule nkqubo,ii-capacitors zefilimufumana usetyenziso kwiindawo ezininzi ezibalulekileyo, kuquka:

●Ukucoca i-EMI
●Ikhonkco le-DC
●Ukucoca okuphumayo
●Itanki eHlaziyiweyo

02 Iimeko zokusetyenziswa kwee-capacitors zefilimu kwi-OBC

YMINIbonelela ngeemveliso ezahlukeneyo ze-capacitor yefilimu ezifanelekileyo kwizicelo zokucoca ze-DC-Link kunye neziphumo. Okuphawulekayo kukuba, zonke ezi mveliso ziqinisekisiwe yi-AEC-Q200 automotive-grade. Ukongeza, i-YMIN ibonelela ngeemodeli ezikhethekileyo ezenzelwe iimeko zobushushu obuphezulu kunye nomswakama ophezulu (THB), inika abaphuhlisi ukuguquguquka okukhulu ekukhetheni amacandelo.

Ii-DC-Link Capacitors

Kwinkqubo ye-OBC, i-DC-Link capacitor ibalulekile kwinkxaso yangoku kunye nokucoca phakathi kwesekethe ye-rectifier kunye ne-DC-DC converter. Umsebenzi wayo oyintloko kukufunxa imisinga ye-pulse ephezulu kwibhasi ye-DC-Link, ukuthintela i-pulse voltages ephezulu kwi-impedance ye-DC-Link kunye nokukhusela umthwalo kwi-overvoltage.

Iimpawu ze-capacitors zefilimu—ezifana nokunyamezelana kwe-voltage ephezulu, i-capacitance enkulu, kunye ne-non-polarity—zenza zibe zilungele ukusetyenziswa kokucoca i-DC-Link.

YMIN'sI-MDP(H)uthotho lukhetho oluhle kakhulu kwii-capacitors ze-DC-Link, ezibonelela:
