Koronto beddelasho oo heer sare ah oo PFC ah ayaa nidaamsan

PFC waa macnaha sixitaanka qodobka korontada, kaas oo inta badan loo isticmaalo in lagu qeexo waxtarka isticmaalka tamarta korontada ee alaabada elektarooniga ah. Inta uu kor u kaco qodobka korontada, ayaa hufnaanta isticmaalka tamarta korontada sii kordheysa.

Waxaa jira laba nooc oo PFC ah: PFC aan firfircoonayn iyo PFC firfircoon. PFC aan firfircoonayn guud ahaan waxay isticmaashaa habka magdhowga inductance si loo yareeyo farqiga marxaladda u dhexeeya hadda aasaasiga ah iyo danabka gelinta AC si loo hagaajiyo qodobka awoodda, laakiin qodobka awoodda ee PFC aan firfircoonayn ma aha mid aad u sarreeya wuxuuna gaari karaa oo keliya 0.7 ~ 0.8; PFC firfircoon wuxuu ka kooban yahay inductance, capacitance iyo qaybo elektaroonik ah, wuxuu gaari karaa ilaa 0.99. Waa yar yahay wuxuuna gaari karaa qodobka awoodda sare, laakiin kharashku wuu ka sarreeyaa kan PFC aan firfircoonayn.

PFC waxaa badanaa loo isticmaalaa sidii koronto firfircoon oo ku jirta PC-ga, PFC-na waxay leedahay astaamaha soo socda ugu yaraan:

1) Danabka la gelinayo wuxuu noqon karaa 90V ilaa 270V;

2) Qodobka awoodda khadka ayaa ka sarreeya 0.98, wuxuuna leeyahay faa'iidooyinka khasaaraha hooseeya iyo isku halaynta sare;

3) PFC-ga IC waxaa sidoo kale loo isticmaali karaa sidii koronto kaabis ah, sidaa darteed transformer-ka heeganka badanaa looma baahna isticmaalka wareegga PFC ee firfircoon;

4) Wax soo saarku isma beddelo marka la isticmaalayo danabka la gelinayo, sidaa darteed waxaa la heli karaa danab wax soo saar oo aad u deggan;

5) Ripple-ka danabka DC-ga ee soo baxaya ee PFC-ga firfircoon aad buu u yar yahay wuxuuna soo bandhigayaa mowjad sine ah oo ah 100Hz / 120Hz (laba jeer oo ka mid ah inta jeer ee korontada). Sidaa darteed, korontada oo adeegsanaysa PFC-ga firfircoon uma baahna inay isticmaasho kaabsoosha shaandhada awoodda weyn leh.

PFC firfircoon wuxuu ka kooban yahay inductance, capacitance iyo qaybo elektaroonik ah. Waxay leedahay mug yar. Waxay habaysaa qaabka hirarka hadda jira iyada oo loo marayo IC gaar ah si loo magdhabo farqiga marxaladda u dhexeeya hadda iyo danabka. PFC firfircoon wuxuu gaari karaa awood sare - badanaa in ka badan 98%, laakiin kharashku sidoo kale waa mid aad u sarreeya. Intaa waxaa dheer, PFC firfircoon ayaa sidoo kale loo isticmaali karaa sidii sahay koronto oo kaaliye ah. Sidaa darteed, isticmaalka wareegga PFC firfircoon, transformer-ka heeganka badanaa looma baahna, gariirka danabka DC ee soo baxa ee PFC firfircoonna aad buu u yar yahay. Korontadani uma baahna inay isticmaasho capacitor shaandheeye awood weyn leh.

Dhawaan waxaan soo saarnay agabyada korontada ee 2000W iyo 3000W oo leh PFC. Qiimuhu aad buu u faa'iido badan yahay. Aad buu uga jaban yahay isla korontada suuqa taal, waxqabadkuna aad buu u deggan yahay. Haddii aad xiisaynayso, fadlan nala soo xiriir. Mahadsanid!
