 Flybacktransformer switching power supplyzvinoreva kuti kana iyo yekutanga coil ye transformer inofara neDC pulse voltage, iyo yechipiri coil yetransformer haipei simba rekubuda kumutoro, asi mushure meiyo excitation voltage yeprimary coil ye transformer yadzimwa.Ipa simba rinobuda, rudzi urwu rwe transformer switching power supply inonzi flyback switching power supply.

Iyo inoshanda musimboti weiyo flyback simba switch: iyo inoenderera uye inomira modhi yeflybackmagetsitaura nezvekushanda mamiriro ekushandura.Mumamiriro ezvinhu akaremerwa zvakakwana, transformer inoshanda mune imwe nzira yekushanda iyo simba rinotamiswa zvachose kana kuti risina kukwana.Kazhinji, dhizaini inofanira kunge yakavakirwa pamamiriro ekushanda.Yakajairika flyback magetsi emagetsi anofanirwa kushanda mune inoenderera modhi, kuitira kuti iyo switching chubhu uye kurasikirwa kwedunhu kudiki, uye kushushikana kwekushanda kwekupinza uye kubuda capacitors kunogona kuderedzwa, asi pane zvimwe zvinosiya.Inoda kutaurwa pano: nekuda kwehunhu hweiyo flyback simba rekupa, zvakare yakanyanya kukodzera kugadzirwa seyakakwira-voltage magetsi, uye iyo yakakwira-voltage magetsi emagetsi transformer kazhinji inoshanda mu discontinuous mode.Ini ndinonzwisisa kuti kubuda kweiyo-high-voltage magetsi kunoda kushandiswa kwepamusoro voltage rectifier diode.Nekuda kwehunhu hwemaitiro ekugadzira, yakakwira reverse voltage diode ine nguva refu yekudzosera kumashure uye yakaderera kumhanya.Mumamiriro ezvinhu anoenderera mberi, diode inopora kana pane kurerekera mberi.Iko kurasikirwa kwesimba panguva yekudzoreredza reverse yakakura kwazvo, iyo isingakodzeri kuita kweshanduko.Iko kunatsurudzwa kwechubhu inodzoreredza kunoderedza kutendeuka kushanda zvakanaka, kupisa zvakanyanyisa chubhu yekudzoreredza uye kunyange kupisa chubhu yekugadziridza.Sezvo mu discontinuous mode, iyo diode inodzokera shure-yakasarudzika pasi pe zero bias, kurasikirwa kunogona kuderedzwa kusvika kune yakaderera.Naizvozvo, iyo yakakwira-voltage simba rekupa inoshanda mu discontinuous mode, uye iyo inoshanda frequency haigone kuve yakanyanya.Kune zvakare rudzi rwe flyback simba rekupa rinoshanda munzvimbo yakaoma.Kazhinji, iyi mhando yemagetsi ekupa inoshanda mu frequency modulation modhi kana mbiri mbiri uye hupamhi modulation modhi.Mamwe anodhura-akaderera ega ega ega ega ega ega ega (rcc) anowanzo shandisa iyi fomu.Kuti uve nechokwadi chekubuda kwakagadzikana, ma transformers Iyo inoshanda frequency inoshanduka neinobuda ikozvino kana yekupinza voltage.Iyo transformer inogara inoramba iri pakati pekuenderera uye inopindirana kana yava pedyo nemutoro wakazara.Rudzi urwu rwemagetsi runongokodzera kune yakaderera-simba kubuda, zvikasadaro iwo electromagnetic kuenderana hunhu huchanetsa kwazvo.
