Ubuhanga bwimbitse | Nigute DC-Ihuza Ubushobozi bwa Firime Zishobora Gukemura Umuvuduko Wamashanyarazi hamwe nimbogamizi zokwizerwa mumashanyarazi ya 800V?

Intangiriro

Mugihe 800V yumurongo wa voltage mwinshi uhinduka mumodoka nshya yingufu, inverter yimashanyarazi itanga ibisabwa cyane kumirongo myinshi iranga ubushobozi bwa DC-Ihuza. Imashini gakondo ya aluminium electrolytike, igarukira kuri ESR yo hejuru hamwe nigisubizo cyayo, ikunda guhura na voltage, bikagabanya imikorere ya sisitemu kandi bikabangamira imikorere yuzuye yibikoresho bya SiC.

Igishushanyo mbonera cyerekana aho iImiyoboro ya DCin inverter

YMIN Ibisubizo bya Filime

- Gutera Imizi Isesengura rya Tekinike - Bitewe nibintu byabo n'imiterere yabyo, capacitori ya aluminium electrolytike isanzwe ifite ESR ndende hamwe na radiyo yo hasi-yonyine (mubisanzwe hafi 4kHz). Mubikorwa byo guhinduranya inshuro nyinshi, ubushobozi bwabo bwo gukurura imiyoboro yumuvuduko mwinshi ntibihagije, byoroshye gutera ihindagurika rya bisi ya bisi, ibyo nabyo bigira ingaruka kumikorere ya sisitemu nubuzima bwibikoresho byamashanyarazi. - Ibisubizo bya YMIN nibyiza byo gutunganya -MDP ya YMINubushobozi bwa firime bukoresha ibikoresho bya firime ya polypropilene hamwe nuburyo bushya bwo guhinduranya kugirango ugere ku bikorwa bikurikira: ESR yagabanutse kugera kuri miliohm, bigabanya cyane igihombo cyo guhinduranya; amajwi ya resonant yongerewe kugeza kuri mirongo ya kHz, ihuza rwose nibisabwa cyane-ibisabwa bya SiC / MOSFETs; kandi ibyiza byabo birimo kwihanganira ingufu nyinshi, kumeneka kwinshi, hamwe nubuzima burebure, bigatuma bikwiranye cyane na voltage nini cyane, ikora cyane-ibidukikije.

- Kugenzura amakuru no kwizerwa Ibisobanuro -

Porogaramu Ikoreshwa na Moderi Yasabwe -

Ikibazo gisanzwe cyo gusaba: Uruganda rukomeye rwa 800V rukora amashanyarazi rukoresha amashanyarazi umunani MDP-800V-15μF mumashanyarazi ya DC-Ihuza umuzenguruko wa disikuru nkuru, igasimbuza neza igisubizo cyambere cya 22 450V ya aluminium electrolytike. Ibi bigabanya agace ka PCB hejuru ya 50%, bigabanya impanuka ya bisi ya bisi 40%, kandi itezimbere imikorere ya sisitemu hafi 1.5%. - Basabwe Icyitegererezo -

Umwanzuro
Urukurikirane rwa YMIN MDP ntabwo rufite ubushobozi bwo gukora cyane ariko nanone ni urufunguzo rukomeye rwa voltage mumashanyarazi menshi, sisitemu nyinshi. Irashobora gufasha injeniyeri gukemura byimazeyo ibibazo byubushakashatsi no kunoza byimazeyo imikorere ya sisitemu no kwizerwa.
