Iyo Flyback Transformer Inofanira Kuvharwa?Ndakabvisa Transformer, Sei Pasina Gap?

Iyo yakakosha yeiyo flyback transformer ndeye yakabatanidzwa inductor, uye kuchengetedza uye kuburitswa kwesimba kunoitwa neimwe nzira.

Iyo yakajairika tsika yeinductor inoshandiswa sekuchengetedza simba ndeyekuvhura gap remhepo.Flyback transformers hazvina kudaro.

Mhedzisiro yekuvhura gap yemhepo yakapetwa kaviri:

1）Dzora iyo inductance, iyo yakakodzera inductance inogona kusangana nezvinodiwa zvekugadzira.
Iyo inductance yakakura uye simba harigone kubhadhariswa.Kana iyo inductance iri diki zvakanyanya, iko kushushikana kweiyo switch chubhu kuchawedzera.

2) Deredza iyo magnetic flux density B.
Tichifunga kuti inductance, yazvino uye magineti zvinhu zvakatemerwa, kuwedzera gap remhepo kunogona kuderedza kushanda kweflux density yeinductor kudzivirira kuzara.
Mushure mekunzwisisa basa rekuvhura gap remhepo, ngationei kana paine flyback transformer isingavhure gap remhepo?
Mhinduro ndeyokuti zvechokwadi hapana mukaha wemhepo.Pane angangoita matatu mamiriro umo gap remhepo haridi kuvhurwa.

A. Iyo chaiyo magnetic core yakasarudzwa yakakura zvikuru kudarika chaiyo inoda.
Ngatiti iwe unogadzira 1W inoshandura uye ukasarudza iyo EE50 musimboti, ipapo mukana wayo wekuzara ndeye zero.
Hapana chikonzero chekuvhura gap remhepo.

B. A powder core magnetic material inosarudzwa, kusanganisira FeSiAl, FeNiMo nezvimwe zvinhu.
Nekuti iyo poda yepakati magineti zvinhu inobvumira kushanda kwemagineti flux density kuti isvike zviuru gumi, iyo yakanyanya kukwirira kupfuura zviuru zvitatu zveyakajairika ferrite.
Zvino kuburikidza nekuverenga kwakaringana, hapana chikonzero chekuvhura gap remhepo uye harizoguti.Kana kuverenga kusina kuitwa nemazvo, inogona kunge ichiri yakazara.

C. Zvikanganiso zvekugadzira kana zvikanganiso zvekugadzirisa.
