Nws tuaj yeem txo cov suab nrov, tshwj xeeb tshaj yog cov suab nrov nrov, los ntawm kev nkag siab txog nws cov laj thawj thiab siv cov tswv yim tsim nyog. Feem ntau ntawm cov suab nrov ua suab nrov hauv PWM hloov hluav taws xob yog tsim los ntawm ob peb lub suab nrov nrov. Cov peev txheej no yooj yim los txheeb xyuas, thiab peb tuaj yeem hloov tus qauv tsim kom txo qis lub zog hluav taws xob lub suab nrov.
Lub voj voog nruab nrab ntawm qhov tam sim no thiab qhov kev sib txuas siab tam sim no ntawm cov ntawv luam tawm Circuit Board yog ib qho ntawm cov suab nrov. RFI hluav taws xob tuaj yeem txo qis los ntawm kev siv cov qauv tsim PCB zoo. Kev nkag siab txog cov khoom siv ntau zaus ntawm cov khoom sib xws thiab PCBs kuj tseem ceeb heev.
Lub input fais fab Circuit Court, uas suav nrog lub hwj chim hloov, thawj winding ntawm, yog thawj qhov tseem ceeb ntawm lub suab nrov.
Lwm qhov tseem ceeb ntawm lub suab nrov yog lub voj uas tsim los ntawm qhov thib ob winding ntawm lub transformer, cov zis rectifier, thiab cov zis lim capacitor. Trapezoidal tam sim no waveforms nrog lub ncov muaj zog kuj txav ntawm cov khoom no. Txhawm rau txo cov suab nrov nrov, cov zis lim capacitor thiab rectifier yuav tsum tau muab ntsia kom ze rau lub transformer raws li qhov ua tau. Ntawm daim phiaj hluav taws xob, cov suab nrov no kuj tsim cov suab nrov nrov.
Cov zis rectifier tus txheej txheem rov qab rov qab yog qhov tseem ceeb ntxiv ntawm lub suab nrov. Hloov lub hwj chim muab lub suab nrov yog cuam tshuam ncaj qha los ntawm lub rectifier qhov rov qab cov khoom. Lub hauv paus ua rau lub suab nrov ntawm lub waveform feem ntau yog rov qab rov qab sai sai. Los ntawm kev koom nrog ib qho absorber nyob rau hauv parallel, nws cov high zaus spectral nta yuav muted.
