Xa kuxoxwa ngezinto ezintsha kunye nokuphuculwa kweenkqubo zokufakelwa kombane kwizithuthi zombane, ingqwalasela idla ngokubekwa kwizinto eziphambili ezifana neyunithi yokulawula kunye nezixhobo zamandla, ngelixa amacandelo ancedisayo njengama-capacitors athambekele ekufumaneni ingqalelo encinci. Nangona kunjalo, la macandelo ancedisayo anempembelelo eqinisekileyo ekusebenzeni ngokubanzi kwenkqubo. Eli nqaku liza kukhangela ukusetyenziswa kwee-capacitors zefilimu ze-YMIN kwiishaja ze-onboard kwaye zihlolisise ukukhethwa kunye nokusetyenziswa kwee-capacitors kwizithuthi zombane.

Phakathi kweentlobo ezahlukeneyo ze-capacitors,i-aluminium electrolytic capacitorsbanembali ende kwaye babambe indawo ebalulekileyo kwinkalo yombane wamandla. Nangona kunjalo, ngokuvela kweemfuno zetekhnoloji, imida ye-electrolytic capacitors iye yabonakala ngakumbi. Ngenxa yoko, enye indlela ephezulu-i-film capacitors-ivele.

Xa kuthelekiswa ne-electrolytic capacitors, ii-film capacitors zibonelela ngeenzuzo ezibalulekileyo malunga nokunyamezela i-voltage, ukuxhathisa okulinganayo okuphantsi kochungechunge (ESR), ukungabikho kwepolarity, uzinzo olomeleleyo, kunye nobomi obude. Ezi mpawu zenza ifilimu capacitors ibalasele ekwenzeni lula uyilo lwenkqubo, iphucula isakhono sangoku, kunye nokubonelela ngokusebenza okuthembekileyo phantsi kweemeko ezirhabaxa zokusingqongileyo.

Itheyibhile: Iinzuzo zokuthelekisa ukusebenza kweiicapacitors zefilimukunye ne-aluminium electrolytic capacitors

Ngokuthelekisa ukusebenza kweefilim capacitors kunye nommandla wokusetyenziswa kwezithuthi zombane, kuyacaca ukuba kukho ukuhambelana okuphezulu phakathi kwezi zibini. Ngaloo ndlela, ii-filimi capacitors ngokungangabazeki ngamacandelo akhethiweyo kwinkqubo yokufakelwa kombane kwizithuthi zombane. Nangona kunjalo, ukuqinisekisa ukufaneleka kwabo kwizicelo zeemoto, ezi capacitors kufuneka zihlangabezane nemigangatho engqongqo yeemoto, ezifana ne-AEC-Q200, kwaye ibonise ukusebenza okuthembekileyo phantsi kweemeko ezinzima. Ngokusekelwe kwezi mfuno, ukukhethwa kunye nokusetyenziswa kwe-capacitors kufuneka kuhambelane nale migaqo.

Inkqubo ye-OBC (On-Board Charger) idla ngokuqulatha amacandelo amabini angundoqo: isekethe yokuhlaziya eguqula umbane ongundoqo we-AC ube yi-DC, kunye ne-DC-DC yokuguqula amandla okwenza umbane ofunekayo we-DC wokutshaja. Kule nkqubo,iicapacitors zefilimufumana isicelo kwiindawo ezininzi eziphambili, kuquka:

●Uhluzo lwe-EMI
●DC-Link
●Uhluzo lweziphumo
●I-Resonant Tank

02 Iimeko zokusetyenziswa kweefilim capacitors kwi-OBC

YMINinikeza uluhlu lweemveliso zefilimu ze-capacitor ezifanelekileyo kwi-DC-Link kunye neziphumo zokucoca izicelo. Ngokucacileyo, zonke ezi mveliso ziqinisekisiweyo yi-AEC-Q200 yeemoto. Ukongeza, i-YMIN ibonelela ngeemodeli ezikhethekileyo ezenzelwe ubushushu obuphezulu kunye nobushushu obuphezulu (THB), inika abaphuhlisi ukuguquguquka okukhulu ekukhetheni icandelo.

I-DC-Link Capacitors

Kwinkqubo ye-OBC, i-DC-Link capacitor iyimfuneko kwinkxaso yangoku kunye nokucoca phakathi kwesekethe yokuhlaziya kunye ne-DC-DC converter. Umsebenzi wayo ophambili kukufunxa imisinga ephezulu ye-pulse kwibhasi ye-DC-Link, ukuthintela i-voltage ephezulu ye-pulse kwi-impedance ye-DC-Link kunye nokukhusela umthwalo kwi-overvoltage.

Iimpawu zendalo zefilimu capacitors-ezifana nokunyamezela kwamandla ombane aphezulu, i-capacitance enkulu, kunye ne-non-polarity-zenza ukuba zilungele izicelo zokucoca i-DC-Link.

YMIN'sMDP(H)uthotho lolona khetho lubalaseleyo kwi-DC-Link capacitors, enikezela:

IiCapacitors zoHlulo lokuPhuma

Ukuphucula iimpawu zokuphendula okwexeshana kwimveliso ye-OBC ye-DC, i-capacitance enkulu, i-ESR esezantsi ye-ESR yemveliso ye-capacitor yokucoca iyafuneka. YMIN ibonelelaI-MDPi-low-voltage DC-Link film capacitors, ebonisa:

Ezi mveliso zibonelela ngokusebenza okugqwesileyo, ukuthembeka, kunye nokulungelelaniswa kwezicelo zemoto ezifunayo, ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokuzinza kwe-OBC.
