Txhawm rau daws cov teeb meem ntawm cov khoom sib nqus thiab cov terminals ntawm cov tsoos ntau yam synchronous rectifiers, integrated magnetic technology yog siv nyob rau hauv no topology. Lub topologies ntawm ob peb magnetic tam sim no rectifiers yog muab piv. Thaum kawg, cov qauv kev sim thiab kev sim waveforms ntawm 1V thiab 20W dc / dc converters tau muab.
Hauv DC / DC converter, vim nws tus kheej cov yam ntxwv, lub dual tam sim no rectifier topology tau dhau los ua qhov zoo tshaj plaws tso zis rectification topology. Piv nrog rau cov tsoos mid-kais rectifier topology, nws sab transformer muaj tsuas yog ib txheej ntawm windings thiab ib tug kuj yooj yim qauv. Nyob rau tib lub sijhawm, tus lej ntawm CDR sab winding kuj tsawg dua. Nyob rau hauv cov ntaub ntawv ntawm high tam sim no, qhov poob ntawm lub thib ob winding yog txo. Cov zis muaj ob lim inductors, thiab tsuas yog ib nrab ntawm cov load tam sim no dhau los ntawm txhua qhov inductor tam sim no, yog li cov zis lim inductor muaj lub zog me me, vim tias muaj ob lub lim inductors thiab cov zis tam sim no / voltage hloov pauv ntawm lub converter kuj me me. . Tab sis nws yuav tsum muaj peb lub ntsiab lus sib nqus, uas ua rau muaj kev nce ntxiv hauv ntim, yog li txo lub zog ceev. Nyob rau tib lub sijhawm, muaj ntau cov kab hluav taws xob terminals. Thaum qhov tam sim no loj, lub zog poob ntawm cov terminals yuav tsum loj heev. Txhawm rau kov yeej cov kev tsis txaus no, kev siv tshuab sib nqus sib nqus tau siv hauv CDR topology. Lub npe hu ua sib nqus sib nqus yog lub converter uas muaj ob lossis ntau qhov kev ywj pheej sib nqus (transformers, input / output filter inductors) nyob rau hauv cov tub ntxhais sib nqus kom txo qhov ntim thiab ua kom lub zog ceev thiab txo cov terminals.
Lub sij hawm-tam sim no synchronous rectification topology tau dav siv nyob rau hauv high-tam sim no converters, tab sis muaj loj defects nyob rau hauv cov qauv ntawm ib txwm sib nqus cov khoom. Yuav kom kov yeej cov kev tsis txaus no, kev siv tshuab sib nqus sib nqus tau siv rau hauv cov txheej txheem no. Nws tau thov. Cov kab lus no sib piv thiab sib piv cov qauv siv hluav taws xob ntau tam sim no, thiab muab cov qauv kev sim ntsuas hluav taws xob sib xws. Nyob rau hauv hnyav load, lub zog khaws cia nyob rau hauv thawj toughness inductance ntawm lub transformer yuav siv tau kom paub tus kheej-tsav ntawm lub thib ob synchronous rectifier.
