Kev Conduction Coupling ntawm hloov hluav taws xob muab khoom tshwj xeeb suav nrog:
1. Hom hom thiab cov qauv sib txawv ntawm cov qauv suab nrov
Nyob rau hauv hloov hom fais fab khoom, hom suab nrov thiab cov khoom siv hluav taws xob sib txawv, thiab cov pob hluav taws xob ua kom muaj zog, thiab cov khoom siv hluav taws xob, kev tsis sib haum xeeb, tus kheej capacitance tsim los ntawm kev sib nrig sib sib txuas ntawm cov luam tawm, ua rau muaj hom thiab hom kev cuam tshuam. Ntawm lub hauv paus ntawm kev txheeb xyuas cov parasitic parameter ua qauv ntawm kev tiv thaiv, thiab capacitance, thiab cov qauv luam tawm, cov qauv luam tawm tam sim no ntawm lub converter tuaj yeem tau txais.
Cov zog siab ua qauv ntawm lub ntsiab ntawm ob lub voj voog
Lub parasitic inductance thiab capacitance sab hauv lub hwj chim raj cuam tshuam rau kev ua tau zoo ntawm Circuit Court. Cov hluav taws xob no ua rau muaj kev cuam tshuam zoo tam sim no kom ntws mus rau cov hlau ua kom huv si, thiab muaj lub plhaw plhaw ck ntawm lub hwj chim thiab cov cua sov. Vim kev nyab xeeb, cov cua sov so feem ib txwm yog qhov tseem ceeb, uas muab cov suab nrov uas muaj ntau yam.
Thaum lub sijhawm ua haujlwm ntawm PWM conterers, hom suab nrov yog tseem tsim nrog nrog kev ua haujlwm ntawm hloov cov khoom siv. Raws li muaj nyob hauv daim duab 1, rau ib nrab choj hloov pauv, cov yeeb tshuaj voltage ntawm mus hloov Q1 yog ib txwm U1, thiab cov peev xwm} thiab U1 / 2 nrog kev hloov pauv ntawm lub xeev mus hloov; Qhov chaw muaj peev xwm ntawm Q2 yog ib txwm 0, thiab cov dej muaj peev xwm sib txawv ntawm {8}} thiab U1 / 2. Txhawm rau kom muaj kev sib tiv tauj zoo ntawm lub hloov raj thiab lub radiator, roadating gaskets lossis insulating silicone lossis insulating silicone nrog zoo silicone nrog zoo silicone nrog zoo silicone lossis insulating gaskets yog feem ntau ntxiv nruab nrab ntawm lub tes hloov thiab radiator. Qhov no txhais tau tias muaj kev sib txuas ua ke txuas capactructitor ck nruab nrab ntawm taw tes a thiab hauv av. Thaum lub xeev ntawm lub tshuab hloov pauv Q1 thiab Q2 hloov pauv ntawm lub ntsej muag sib luag, thiab muaj cov suab nrov uas muaj suab nrov tam sim no ua rau muaj hluav taws xob Coupling impedance z nruab nrab hauv av thiab kab loj, sib sau hom suab nrov.
