Ubushobozi bwa firime bufasha tekinoroji ya SiC na IGBT gutera imbere byihuse: Ibisubizo bya YMIN

Mu myaka yashize, iterambere ryateye imbere mu nganda nshya z’ingufu nko kubika amafoto y’amashanyarazi n’imodoka zikoresha amashanyarazi (EV) byatumye ubwiyongere bukabije bukenerwa n’ubushobozi bwa DC-Link. Muri make, ubushobozi bwa DC-Ihuza bigira uruhare runini mukuzunguruka. Barashobora gukurura umuyaga mwinshi hejuru ya bisi hanyuma bagahindura voltage ya bisi, bakemeza ko IGBT na SiC MOSFET byahinduwe birindwa ingaruka mbi zumuvuduko mwinshi hamwe numuvuduko wigihe gito mugihe ukora.

Mugihe ingufu za bisi zimodoka nshya ziyongera ziva kuri 400V zikagera kuri 800V, icyifuzo cya capacator za firime cyiyongereye cyane. Nk’uko imibare ibigaragaza, ubushobozi bwashyizweho bw’imashanyarazi ikoresha amashanyarazi bushingiye kuri DC-Link yoroheje ya firime yageze kuri miliyoni 5.1117 mu 2022, bingana na 88.7% by’ubushobozi bwashyizweho bwo kugenzura amashanyarazi. Inverteri yimashini yibigo byinshi bigenzura amashanyarazi nka Tesla na Nidec byose bikoresha imashini ya firime ya DC-Link, bingana na 82.9% yubushobozi bwashyizweho kandi byahindutse inzira nyamukuru kumasoko yo gutwara amashanyarazi.

Impapuro zubushakashatsi zerekana ko muri silicon IGBT igice cy-ikiraro gihindura, imiyoboro gakondo ya electrolytike ikoreshwa muguhuza DC, ariko umuvuduko wa voltage uzaba bitewe na ESR ndende ya capacitori ya electrolytique. Ugereranije na silicon ishingiye kuri IGBT ibisubizo, SiC MOSFETs ifite inshuro nyinshi zo guhinduranya, bityo rero amplitude amplitude amplitude mumashanyarazi ya DC ihuza igice cyikiraro cya kiraro kiri hejuru, gishobora gutera imikorere yibikoresho cyangwa kwangirika, kandi numurongo wa resonant ya capacitori ya electrolytike ni 4kHz gusa, idahagije kugirango ikureho ibintu bya SiC MOSFET.

Kubwibyo, muri porogaramu za DC nkibikoresho byo gutwara amashanyarazi hamwe na fotora ya fotora hamwe nibisabwa byizewe,ubushobozi bwa firimeByahiswemo. Ugereranije na capacitori ya aluminium electrolytike, ibyiza byayo ni imbaraga zo guhangana n’umuvuduko mwinshi, ESR yo hasi, kutagira polarite, imikorere ihamye, hamwe nubuzima burebure, bityo ukagera ku kurwanya imbaraga zikomeye no gushushanya sisitemu yizewe.

Sisitemu ikoresha ubushobozi buke bwa firime irashobora kwifashisha inshuro nyinshi no gutakaza bike kwa SiC MOSFETs no kugabanya ubunini nuburemere bwibigize pasiporo. Ubushakashatsi bwa Wolfspeed bwerekana ko inverter ya IGBT ya silikoni 10kW ikenera imashini ya aluminium electrolytike 22, mu gihe inverter ya 40kW SiC isaba gusa imashini 8 zoroshye, kandi agace ka PCB nako kagabanutse cyane.

Mu rwego rwo gusubiza isoko, YMIN Electronics yatangijeMDP ikurikirana ya firime, ikoresha tekinoroji igezweho nibikoresho byujuje ubuziranenge kugirango ihuze na SiC MOSFET na IGBT ishingiye kuri silicon. Ubushobozi bwa MDP bwerekana ubushobozi bwa ESR buke, kwihanganira ingufu nyinshi, umuvuduko muke hamwe nubushyuhe bwo hejuru.

Ibyiza bya YMIN Electronics 'ibicuruzwa bya firime capacitor ：

Igishushanyo cya YMIN Electronics yerekana ubushobozi bwa ESR kugirango igabanye imbaraga za voltage no gutakaza ingufu mugihe cyo guhinduranya no kunoza imikorere ya sisitemu. Ifite voltage nini cyane, ihuza na voltage nini cyane, kandi iremeza sisitemu ihamye.

Imiyoboro ya MDP ikurikirana ifite ubushobozi bwa 1uF-500uF hamwe na voltage ya 500V kugeza 1500V. Bafite imyuka yo hasi yamashanyarazi nubushyuhe bwo hejuru. Binyuze mu bikoresho byujuje ubuziranenge hamwe nuburyo bugezweho, uburyo bwiza bwo gukwirakwiza ubushyuhe bwateguwe kugirango habeho imikorere ihamye ku bushyuhe bwo hejuru, kongera ubuzima bwa serivisi, no gutanga inkunga yizewe ya sisitemu ya elegitoroniki. Igihe kimwe ,.Ububiko bwa MDPni ntoya mubunini, hejuru yubucucike bwimbaraga, kandi ikoresha uburyo bushya bwo gukora firime yoroheje kugirango iteze imbere sisitemu nogukora neza, kugabanya ingano nuburemere, no kongera ibikoresho byoroshye kandi byoroshye.

YMIN Electronics DC-Ihuza firime ya capacitori ya seriveri ifite iterambere rya 30% mukwihanganira dv / dt no kwiyongera kwa 30% mubuzima bwa serivisi, bitezimbere ubwizerwe bwumuzunguruko wa SiC / IGBT, bizana neza-bikoresha neza, kandi bikemura ikibazo cyibiciro.
