PFC yo hejuru yagengaga guhinduranya amashanyarazi

PFC ni igisobanuro cyo gukosora ibintu, bikoreshwa cyane cyane kuranga imikoreshereze yingufu zamashanyarazi nibicuruzwa bya elegitoroniki.Iyo imbaraga zingana ninshi, niko gukoresha ingufu z'amashanyarazi.

Hariho ubwoko bubiri bwa PFC: pasifike ya PFC na PFC ikora.Passive PFC isanzwe ikoresha uburyo bwo kwishyura induction kugirango igabanye itandukaniro ryicyiciro hagati yumuvuduko wibanze na voltage yinjiza AC kugirango itezimbere ingufu, ariko ibintu byingufu za pasifike PFC ntabwo biri hejuru cyane kandi birashobora kugera kuri 0.7 ~ 0.8;Active PFC igizwe na inductance, capacitance nibikoresho bya elegitoronike, irashobora kugera kuri 0.99.Nibito kandi birashobora kugera kubintu byinshi byingufu, ariko ikiguzi kiri hejuru yicyiza cya PFC.

PFC ikoreshwa kenshi nkibikoresho bitanga amashanyarazi muri PC, kandi PFC ifite ibimenyetso bikurikira byibuze:

1) Umuvuduko winjiza urashobora kuva kuri 90V kugeza 270V;

2) Imbaraga zumurongo ziri hejuru ya 0,98, kandi ifite ibyiza byo gutakaza bike no kwizerwa cyane;

3) PFC ya IC irashobora kandi gukoreshwa nkamashanyarazi yingoboka, kubwibyo rero impinduka zihagarara akenshi ntizisabwa mugukoresha imiyoboro ikora ya PFC;

4) Ibisohoka ntabwo bihindagurika hamwe ninjiza yinjiza, bityo imbaraga zishobora gusohoka cyane zishobora kuboneka;

5) Ibisohoka DC voltage ripple ya PFC ikora ni nto cyane kandi itanga umurongo wa sine wa 100Hz / 120Hz (inshuro ebyiri z'umurongo w'amashanyarazi).Kubwibyo, amashanyarazi akoresha PFC ikora ntabwo akeneye gukoresha ubushobozi bunini bwo kuyungurura ubushobozi.

PFC ikora igizwe na inductance, capacitance hamwe nibikoresho bya elegitoroniki.Ifite ingano nto.Ihindura ibyerekezo byubu binyuze muri IC idasanzwe kugirango yishyure itandukaniro ryicyiciro hagati yumuvuduko na voltage.PFC ikora irashobora kugera kubintu byinshi - mubisanzwe birenga 98%, ariko ikiguzi nacyo kiri hejuru.Mubyongeyeho, PFC ikora irashobora kandi gukoreshwa nkumuriro wamashanyarazi.Kubwibyo, mugukoresha umuzenguruko wa PFC ukora, transformateur ya standby akenshi ntabwo isabwa, kandi impinduramatwara isohoka DC voltage ya PFC ikora ni nto cyane.Amashanyarazi ntabwo akeneye gukoresha ubushobozi bunini bwo kuyungurura ubushobozi.

Duherutse gushyira ahagaragara 2000W na 3000W yo guhindura amashanyarazi hamwe na PFC.Igiciro ni cyiza cyane.Nibihendutse cyane kuruta amashanyarazi amwe kumasoko, kandi imikorere irahagaze neza.Niba ubishaka, twandikire.Murakoze!
