POT3019 High zaus Fais fab Transformer

Nyob rau hauv kev tsim ntawm high-frequency transformer, lub leakage inductance thiab faib capacitance ntawm transformer yuav tsum tau tsawg, vim hais tias lub high-frequency transformer nyob rau hauv switching fais fab mov xa high-frequency mem tes square wave signals. Nyob rau hauv cov txheej txheem ntawm kev sib kis, cov xau inductance thiab kev faib tawm yuav ua rau muaj qhov hluav taws xob tam sim no thiab qhov siab tshaj plaws, nrog rau cov oscillation sab saum toj, uas ua rau poob ntau ntxiv. Feem ntau, cov xau inductance ntawm transformer yog tswj raws li 1% ~ 3% ntawm thawj inductance. Leakage inductance ntawm thawj kauj-tshwj xeeb inductance ntawm transformer yog tshwm sim los ntawm kev sib txuas tsis tiav ntawm cov hlau nplaum sib nqus ntawm cov kauj vab thib ob thiab cov coil thib ob, nruab nrab ntawm cov txheej, thiab nruab nrab ntawm cov lem. Distributed capacitance-Lub capacitance tsim ntawm lem ntawm transformer winding, nruab nrab ntawm sab sauv thiab qis txheej ntawm tib winding, ntawm txawv windings, thiab ntawm windings thiab shielding txheej yog hu ua faib capacitance. Thawj winding-Cov thawj winding yuav tsum tau muab tso rau hauv lub innermost txheej, yog li ntawd qhov ntev ntawm cov hlau siv nyob rau hauv txhua txhua tig ntawm lub transformer thawj winding yuav luv tshaj plaws, thiab cov hlau siv nyob rau hauv tag nrho cov winding yuav txo tau, uas zoo txo ​​tau qhov zoo tshaj plaws winding. faib capacitance ntawm thawj winding nws tus kheej. Secondary winding-Tom qab thawj winding yog qhov txhab, nws yuav tsum tau ntxiv (3 ~ 5) txheej ntawm rwb thaiv tsev hauv ob sab phlu ua ntej winding qhov thib ob winding. Qhov no tuaj yeem txo qhov capacitance ntawm kev faib cov capacitor ntawm thawj winding thiab theem nrab winding, thiab tseem ua rau kom lub zog rwb thaiv tsev ntawm thawj winding thiab theem nrab winding, uas ua tau raws li qhov yuav tsum tau ntawm rwb thaiv tsev thiab voltage kuj. Bias winding-txawm hais tias qhov bias winding yog qhov txhab ntawm lub hauv paus thiab theem nrab lossis txheej txheej sab nraud yog cuam tshuam txog seb qhov kev hloov pauv ntawm lub zog hloov pauv yog raws li qhov nruab nrab voltage lossis thawj qhov hluav taws xob.
