Flybacktransformer hloov fais fab movtxhais tau hais tias thaum thawj kauj ntawm lub transformer zoo siab los ntawm DC pulse voltage, theem nrab kauj ntawm lub transformer tsis muab lub zog tso zis rau lub load, tab sis tsuas yog tom qab lub excitation voltage ntawm thawj kauj ntawm lub transformer yog muab tua.Muab lub zog tso zis, hom transformer hloov fais fab mov yog hu ua flyback switching fais fab mov.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm flyback fais fab hloov: cov qauv txuas ntxiv thiab tsis txuas ntxiv ntawm flybackfais fab movxa mus rau lub xeev ua haujlwm ntawm lub transformer.Nyob rau hauv lub xeev loaded tag nrho, lub transformer ua hauj lwm nyob rau hauv ib tug ua hauj lwm hom nyob rau hauv uas lub zog yog kiag li hloov los yog tsis tiav hloov.Feem ntau, kev tsim qauv yuav tsum ua raws li qhov chaw ua haujlwm.Cov khoom siv hluav taws xob flyback yuav tsum ua hauj lwm nyob rau hauv tas li ntawd, kom lub switching tube thiab Circuit Court poob yog me me, thiab kev ua hauj lwm kev nyuaj siab ntawm input thiab output capacitors yuav txo tau, tab sis muaj ib co kev zam.Nws yuav tsum tau taw qhia rau ntawm no: vim yog cov yam ntxwv ntawm flyback fais fab mov, nws kuj yog tsim nyog los tsim raws li ib tug high-voltage fais fab mov, thiab high-voltage fais fab mov transformer feem ntau ua hauj lwm nyob rau hauv discontinuous hom.Kuv nkag siab tias qhov tso zis ntawm high-voltage fais fab mov yuav tsum tau siv high voltage rectifier diodes.Vim yog cov yam ntxwv ntawm cov txheej txheem tsim khoom, siab rov qab voltage diodes muaj lub sij hawm rov qab mus ntev thiab qis ceev.Nyob rau hauv lub xeev tas mus li tam sim no, lub diode rov qab thaum muaj kev tsis ncaj ncees rau pem hauv ntej.Lub zog poob thaum rov qab rov qab yog qhov loj heev, uas tsis zoo rau kev ua haujlwm ntawm lub converter.Kev txhim kho ntawm lub raj rectifier yuav txo tau qhov kev hloov pauv hloov, ua kom sov lub raj rectifier thiab txawm hlawv lub raj rectifier.Txij li thaum nyob rau hauv hom discontinuous, lub diode yog thim rov qab-biased nyob rau hauv xoom bias, qhov poob yuav raug txo kom tsawg.Yog li ntawd, cov khoom siv hluav taws xob high-voltage ua haujlwm nyob rau hauv hom tsis tu ncua, thiab kev khiav hauj lwm zaus tsis tuaj yeem siab dhau.Kuj tseem muaj hom flyback fais fab mov uas ua haujlwm hauv lub xeev tseem ceeb.Feem ntau, hom khoom siv fais fab no ua haujlwm nyob rau hauv zaus hloov pauv hom lossis dual zaus thiab qhov dav hloov pauv hom.Qee cov khoom siv hluav taws xob zoo siab rau tus kheej (rcc) feem ntau siv daim ntawv no.Txhawm rau kom ntseeg tau tias cov zis ruaj khov, transformers Kev khiav hauj lwm zaus hloov nrog cov zis tam sim no lossis cov khoom siv hluav taws xob.Lub transformer ib txwm nyob nruab nrab ntawm qhov nruam thiab sib tshuam thaum nws nyob ze rau tag nrho cov load.Hom kev siv fais fab no tsuas yog tsim rau cov zis hluav taws xob tsawg, txwv tsis pub cov yam ntxwv ntawm electromagnetic compatibility yuav teeb meem heev.
