Babban wutar lantarki mai sarrafa wutar lantarki ta PFC

PFC shine ma'anar gyaran wutar lantarki, wanda galibi ana amfani da shi don kwatanta ingancin amfani da wutar lantarki ta samfuran lantarki. Mafi girman ƙarfin wutar lantarki, mafi girman ingancin amfani da wutar lantarki.

Akwai nau'ikan PFC guda biyu: passive PFC da active PFC. Passive PFC gabaɗaya yana amfani da hanyar ramawa ta inductance don rage bambancin lokaci tsakanin ainihin wutar lantarki da ƙarfin wutar lantarki na shigarwar AC don inganta ƙarfin wutar lantarki, amma ƙarfin PFC ba shi da yawa kuma yana iya kaiwa 0.7 ~ 0.8 kawai; Active PFC ya ƙunshi inductance, capacitance da kayan lantarki, yana iya kaiwa har zuwa 0.99. Ƙarami ne kuma yana iya cimma babban ƙarfin lantarki, amma farashin ya fi na passive PFC.

Sau da yawa ana amfani da PFC a matsayin wutar lantarki mai aiki a PC, kuma PFC yana da halaye masu zuwa aƙalla:

1) Ƙarfin wutar lantarki na shigarwa zai iya kasancewa daga 90V zuwa 270V;

2) Ƙarfin layin ya fi 0.98 girma, kuma yana da fa'idodin ƙarancin asara da aminci mai yawa;

3) Ana iya amfani da PFC na IC a matsayin ƙarin wutar lantarki, don haka sau da yawa ba a buƙatar na'urar canza wutar lantarki ta jiran aiki wajen amfani da da'irar PFC mai aiki;

4) Fitowar ba ta canzawa tare da ƙarfin shigarwa, don haka ana iya samun ƙarfin fitarwa mai ƙarfi;

5) Ƙarfin wutar lantarki na DC na PFC mai aiki ƙanƙanta ne kuma yana nuna raƙuman sine na 100Hz / 120Hz (sau biyu fiye da mitar wutar lantarki). Saboda haka, wutar lantarki ta amfani da PFC mai aiki ba ta buƙatar amfani da babban ƙarfin matatar mai ƙarfi.

PFC mai aiki ya ƙunshi inductance, capacitance da kayan lantarki. Yana da ƙaramin girma. Yana daidaita yanayin raƙuman ruwa ta hanyar IC na musamman don rama bambancin lokaci tsakanin halin yanzu da ƙarfin lantarki. PFC mai aiki zai iya cimma babban ƙarfin lantarki - yawanci fiye da 98%, amma farashin kuma yana da yawa. Bugu da ƙari, ana iya amfani da PFC mai aiki azaman tushen wutar lantarki mai taimako. Saboda haka, a cikin amfani da da'irar PFC mai aiki, sau da yawa ba a buƙatar na'urar canza wutar lantarki ta jiran aiki, kuma ripple na ƙarfin wutar lantarki na DC na PFC mai aiki ƙarami ne. Wannan samar da wutar lantarki ba ya buƙatar amfani da babban capacitor mai ƙarfi.

Kwanan nan mun ƙaddamar da samar da wutar lantarki mai ƙarfin 2000W da 3000W tare da PFC. Farashin yana da fa'ida sosai. Ya fi rahusa fiye da samar da wutar lantarki iri ɗaya a kasuwa, kuma aikin yana da ƙarfi sosai. Idan kuna sha'awar sa, da fatan za a tuntuɓe mu. Na gode!
