Capacitors za filime zifasha ikoranabuhanga rya SiC na IGBT gutera imbere vuba: Ibisubizo byo gukoresha capacitors za YMIN

Mu myaka ya vuba aha, iterambere ry’inganda nshya z’ingufu nka ububiko bw’amashanyarazi n’imodoka zikoresha amashanyarazi (EVs) ryatumye umubare munini w’abakenera capacitors za DC-Link wiyongera cyane. Muri make, capacitors za DC-Link zigira uruhare runini mu muyoboro w’amashanyarazi. Zishobora gufata umuvuduko mwinshi w’amashanyarazi ku mpera ya bisi no koroshya umuvuduko w’amashanyarazi wa bisi, zigatuma IGBT na SiC MOSFET birindwa ingaruka mbi z’umuvuduko mwinshi w’amashanyarazi n’umuvuduko w’amashanyarazi mu gihe cy’akazi.

Uko ingufu za bisi z’imodoka nshya zikoresha ingufu ziyongera kuva kuri 400V kugeza kuri 800V, icyifuzo cya capacitors za filime cyariyongereye cyane. Dukurikije amakuru, ubushobozi bwa mashini zikoresha amashanyarazi zishingiye kuri capacitors za DC-Link thin-film bwageze kuri miliyoni 5.1117 mu 2022, bungana na 88.7% by’ubushobozi bwashyizweho bwo kugenzura amashanyarazi. Imashini zikoresha amashanyarazi zo mu bigo byinshi bikomeye bigenzura amashanyarazi nka Tesla na Nidec zose zikoresha capacitors za filime za DC-Link, zigize 82.9% by’ubushobozi bwashyizweho kandi zikaba ari zo zikunze kugaragara ku isoko ry’amashanyarazi.

Inyandiko z'ubushakashatsi zigaragaza ko muri silicon IGBT half-bridge inverters, capacitors gakondo za electrolytic zikoreshwa muri DC link, ariko kwiyongera k'umuvuduko w'amashanyarazi kuzaba bitewe na ESR iri hejuru ya capacitors za electrolytic. Ugereranyije na silicon-based IGBT solutions, SiC MOSFETs zifite frequency yo guhinduranya iri hejuru, bityo voltage surge amplitude muri DC link ya half-bridge inverter ni nyinshi, bishobora gutuma imikorere y'igikoresho yangirika cyangwa ndetse no kwangirika, kandi frequency ya resonant ya capacitors za electrolytic ni 4kHz gusa, ibi bikaba bidahagije kugira ngo byinjize umuvuduko w'amashanyarazi ya SiC MOSFET inverters.

Kubwibyo, mu bikorwa bya DC nka inverters zikoresha amashanyarazi na inverters zifite ubushobozi bwo kwizerwa cyane,capacitors za filimeakenshi bitoranywa. Ugereranyije na capacitors za electrolytic za aluminium, ibyiza byazo mu mikorere ni ukurwanya voltage nyinshi, ESR nke, kudakoresha polarity, imikorere ihamye, no kuramba, bityo bigatuma habaho ubudahangarwa bukomeye bw'amajwi n'imiterere yizewe ya sisitemu.

Sisitemu zikoresha capacitors za thin-film zishobora kubyaza umusaruro frequency nyinshi n'igihombo gito cya SiC MOSFETs no kugabanya ingano n'uburemere bw'ibice bidakora. Ubushakashatsi bwa Wolfspeed bwerekana ko inverter ya IGBT ya 10kW ishingiye kuri silicon ikenera capacitors 22 za aluminium electrolytic, mu gihe inverter ya SiC ya 40kW ikenera capacitors 8 za thin-film gusa, kandi agace ka PCB nako karagabanutse cyane.

Mu rwego rwo gusubiza icyifuzo cy'isoko, YMIN Electronics yatangijeurukurikirane rwa MDP rwa capacitors za filime, zikoresha ikoranabuhanga rigezweho n'ibikoresho byiza kugira ngo zihuze na SiC MOSFET na IGBT ishingiye kuri silicon. Capacitors za MDP zifite ESR nkeya, voltage ikomeye, umuyoboro muto w'amazi n'ubushyuhe bwinshi.

Ibyiza by'ibicuruzwa bya capacitor ya filimi ya YMIN Electronics:

Igishushanyo mbonera cya capacitor ya filimi ya YMIN Electronics gikoresha igitekerezo cya ESR nke kugira ngo kigabanye stress ya voltage n'ibura ry'ingufu mu gihe cyo guhinduranya no kunoza imikorere myiza y'ingufu za sisitemu. Ifite voltage ifite urwego rwo hejuru, ihuza n'ibidukikije bifite voltage nyinshi, kandi ikanatuma sisitemu ihora ihamye.

Capacitors za MDP zifite ubushobozi bwo gukora kuva kuri 1uF-500uF n'uburebure bwa voltage kuva kuri 500V kugeza kuri 1500V. Zifite umuvuduko muto wo gusohoka n'ubushyuhe buri hejuru. Binyuze mu bikoresho byiza n'imikorere igezweho, imiterere myiza yo gukwirakwiza ubushyuhe yagenewe kwemeza ko imikorere ihamye mu bushyuhe bwinshi, kongera igihe cyo gukora, no gutanga inkunga yizewe ku buryo bw'ikoranabuhanga. Muri icyo gihe,Capacitors za MDP seriesni ntoya mu bunini, zifite ingufu nyinshi, kandi zikoresha uburyo bushya bwo gukora ibikoresho bito kugira ngo zinoze guhuza no gukora neza sisitemu, zigabanye ingano n'uburemere, kandi zongere ubushobozi bwo gutwara no koroshya ibikoresho.

YMIN Electronics DC-Link film capacitor series ifite iterambere rya 30% mu kwihanganira dv/dt ndetse n'ubwiyongere bwa 30% mu gihe cyo kuyikoresha, ibi bikaba byongera ubwizerwe bwa SiC/IGBT circuits, bikazana uburyo bworoshye bwo kuyikoresha, kandi bigakemura ikibazo cy'ibiciro.
