Qhov teeb meem ntawm lub peev xwm tsis zoo ntawm AC switching fais fab mov
1. Yog vim li cas rau qhov tsis muaj peev xwm ntawm AC fais fab mov
AC fais fab mov tuaj yeem ua haujlwm ib txwm thaum nws tsuas yog muab lub zog rau lub motherboard thiab lub floppy drive. Thaum lub hard disk thiab optical drive txuas nrog, lub vijtsam tig dawb thiab tsis tuaj yeem ua haujlwm ib txwm.
Cov laj thawj uas ua tau yog raws li hauv qab no: qhov chaw khiav hauj lwm ntawm transistor tsis raug xaiv kom raug, lub siab-voltage lim capacitor yog to los yog puas, Zener diode yog rhuab thiab leaked, thiab rectifier diode puas.
Cov saum toj no txheeb xyuas qhov tshwm sim thiab feem ntau ua rau tsis zoo AC fais fab nqi peev.
2. Kev daws teeb meem tsis zoo ntawm AC fais fab mov
Hloov txhua lub transistor nyob rau hauv lub oscillation Circuit Court kom nws nce, los yog nce qhov chaw khiav hauj lwm ntawm lub transistor. Tom qab kuaj pom cov khoom tsis raug nrog lub multimeter, hloov lub thyristor, Zener diode, high-voltage lim capacitor lossis rectifier diode.
Ib nrab ntawm cov nuj nqis peev ntawm AC fais fab mov tuaj yeem daws tau los ntawm cov txheej txheem saum toj no. Yog tias nws tseem tsis tuaj yeem daws tau, ces nws yog qhov yuav tsum tau hu rau cov kws tshaj lij thiab cov kws tshaj lij, thiab lawv yuav daws qhov txhaum.
