Switching fais fab mov siab zaus Circuit Court thaiv cov qauv
Switching fais fab mov ua hauj lwm nyob rau hauv high zaus, siab pulse xeev, belongs rau ib tug tshwj xeeb hom analogue circuits. Kev teeb tsa ntawm lub rooj tsavxwm yuav tsum ua raws li cov hauv paus ntsiab lus ntawm high-frequency circuit wiring.
1, layout: mem tes voltage kab luv li sai tau, uas input hloov mus rau lub transformer kab, cov zis transformer mus rau lub rectifier kev twb kev txuas kab. Pulse tam sim no voj me me li sai tau, xws li input lim capacitance zoo rau lub transformer mus rau lub switching raj rov qab capacitance tsis zoo. Cov zis ib feem ntawm lub transformer tso zis mus rau lub rectifier rau cov zis tam sim no mus rau cov zis capacitor rov qab transformer circuit X capacitor yuav tsum nyob ze li sai tau rau cov tswv yim ntawm lub switching fais fab mov, cov input kab yuav tsum tau zam thiab lwm yam circuits parallel, yuav tsum tau. zam. Y capacitor yuav tsum muab tso rau hauv lub chassis av davhlau ya nyob twg los yog FG kev twb kev txuas. Khaws ib qho kev ncua deb ntawm qhov sib chwv inductor thiab transformer kom tsis txhob sib nqus sib nqus. Yog tias nws tsis zoo los cuam tshuam nrog kev sib chwv inductance thiab transformer ntxiv cov ntaub thaiv npog ntawm cov khoom saum toj no muaj kev cuam tshuam ntau dua rau EMC kev ua tau zoo ntawm kev hloov hluav taws xob.
Output capacitance feem ntau siv ob lub rectifier nyob ze rau lwm qhov yuav tsum nyob ze rau cov zis terminals, tuaj yeem cuam tshuam rau lub zog hluav taws xob tso zis ripple ntsuas, ob lub peev xwm me me hauv qhov sib npaug yuav tsum zoo dua li lub peev xwm loj. Thaum tshav kub kub-tsim cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob electrolytic kom tswj tau ib qho kev ncua deb kom ntev lub neej ntawm lub tshuab, electrolytic capacitors yog lub zog hloov hluav taws xob lub neej ntawm lub raj mis, xws li transformers, hwj chim raj, siab zog resistors thiab electrolytic deb, electrolytic qhov chaw ntawm lub tshav kub dissipation yuav tsum tau sab laug, tej yam kev mob tso cai yuav muab tso rau hauv lub cua kom tsawg.
Kev tswj xyuas yuav tsum tau them sai sai rau: siab impedance tsis muaj zog lub teeb liab kev sib txuas kom luv li sai tau, xws li cov qauv kev tawm tswv yim lub voj, thaum soj ntsuam nrog kom tsis txhob cuam tshuam, cov qauv ntsuas hluav taws xob tam sim no, tshwj xeeb tshaj yog tam sim no-tswj circuits, ua haujlwm tsis zoo. qee qhov kev huam yuaj tsis txaus ntseeg, nrog rau kev hloov lub raj tsav lub teeb liab Circuit Court, lub raj xa hluav taws xob hloov hluav taws xob yuav tsum nyob ze rau ntawm lub raj xa hluav taws xob los txhim kho cov hloov raj kev ntseeg siab, uas cuam tshuam rau lub siab DC impedance voltage tsav cov yam ntxwv ntawm lub zog MOSFETs. DC impedance voltage tsav yam ntxwv.
