I-PFC ephezulu elawula ukushintshwa kwamandla kagesi

I-PFC incazelo yokulungiswa kwesici samandla, esetshenziswa kakhulu ukukhombisa ukusebenza kahle kokusetshenziswa kwamandla kagesi ngemikhiqizo kagesi.Ukuphakama kwesici samandla, kuyanda ukusebenza kahle kokusetshenziswa kwamandla kagesi.

Kunezinhlobo ezimbili ze-PFC: i-PFC esebenzayo kanye ne-PFC esebenzayo.I-Passive PFC ngokuvamile isebenzisa indlela yesinxephezelo se-inductance ukuze kuncishiswe umehluko wesigaba phakathi kwamandla ayisisekelo kanye ne-voltage yokokufaka kwe-AC ukuze kuthuthukiswe isici samandla, kodwa isici samandla se-PFC engenzi lutho asiphezulu kakhulu futhi singafinyelela kuphela ku-0.7 ~ 0.8;I-PFC esebenzayo yakhiwe nge-inductance, capacitance kanye nezingxenye ze-elekthronikhi, ingafinyelela ku-0.99.Incane futhi ingafinyelela isici samandla aphezulu, kodwa izindleko ziphakeme kunalezo ze-PFC engenzi lutho.

I-PFC ivame ukusetshenziswa njengamandla asebenzayo ku-PC, futhi i-PFC inezici ezilandelayo okungenani:

1) I-voltage yokufaka ingaba kusuka ku-90V kuya ku-270V;

2) Isici samandla omugqa singaphezu kuka-0.98, futhi sinezinzuzo zokulahlekelwa okuphansi nokuthembeka okuphezulu;

I-3) I-PFC ye-IC ingasetshenziswa futhi njengomthombo wamandla asizayo, ngakho-ke isiguquli esilindile ngokuvamile asidingeki ekusetshenzisweni kwesekethe ye-PFC esebenzayo;

4) Okukhiphayo akuguquguquki nge-voltage yokufaka, ngakho-ke i-voltage ephumayo ezinzile ingatholakala;

5) I-DC voltage ripple ephumayo ye-PFC esebenzayo incane kakhulu futhi iveza i-sine wave engu-100Hz / 120Hz (okuphindwe kabili imvamisa yamandla).Ngakho-ke, ukunikezwa kwamandla okusebenzisa i-PFC esebenzayo akudingi ukusebenzisa i-capacitor enkulu yesihlungi.

I-PFC esebenzayo yakhiwe nge-inductance, capacitance kanye nezingxenye ze-elekthronikhi.Inomthamo omncane.Ilungisa i-waveform yamanje nge-IC ekhethekile ukunxephezela umehluko wesigaba phakathi kwamanje ne-voltage.I-PFC esebenzayo ingafinyelela isici samandla aphezulu - ngokuvamile ngaphezu kwama-98%, kodwa izindleko nazo ziphakeme kakhulu.Ngaphezu kwalokho, i-PFC esebenzayo ingasetshenziswa futhi njengomthombo wamandla asizayo.Ngakho-ke, ekusetshenzisweni kwesekethe ye-PFC esebenzayo, i-transformer yokulinda ngokuvamile ayidingeki, futhi i-ripple ye-voltage ye-DC ephumayo ye-PFC esebenzayo incane kakhulu.Lokhu kunikezwa kwamandla akudingi ukusebenzisa i-capacitor yokuhlunga umthamo omkhulu.

Sisanda kwethula i-2000W kanye ne-3000W ukushintshanisa amandla kagesi nge-PFC.Intengo inenzuzo kakhulu.Kushibhe kakhulu kunokunikezwa kwamandla okufanayo emakethe, futhi ukusebenza kuzinzile kakhulu.Uma unentshisekelo kukho, sicela usithinte.Ngiyabonga!
