Yuav Ua Li Cas Tsim Ib Lub Siab - Muaj Peev Xwm Hloov Hloov Fais Fab?
Hauv kev sib txuas lus thiab lub zog, qhov yuav tsum tau muaj DC lub zog hluav taws xob tso tawm qhov sib txawv tam sim no thiab qhov hluav taws xob. Rau cov khoom siv hluav taws xob muaj peev xwm loj, ntau lub peev xwm me me fais fab mov ntawm tib theem voltage feem ntau txuas nrog rau qhov sib npaug. Txawm li cas los xij, yog tias muaj ntau cov khoom siv hluav taws xob sib txuas ntau dhau, nws tsis tsim nyog rau kev sib koom tam sim no thiab kev ntseeg tau. Yog li ntawd, cov neeg siv urgently thov kom qhov tshwm sim ntawm loj muaj peev xwm muab modules. Raws li keeb kwm yav dhau los no, tus neeg sau tau tsim lub peev xwm loj hloov hluav taws xob. Tam sim no, lub peev xwm loj hloov pauv cov khoom siv hluav taws xob feem ntau yog tsim los ntawm lub ntsiab Circuit Court thiab tswj Circuit Court, thaum cov khoom siv ntse hloov hluav taws xob feem ntau muaj cov lej tswj cov lej tsim los ntawm microcomputer - thaum paub txog cov haujlwm ntse, qee qhov tsis tseem ceeb thiab ntau yam teeb meem txhaum cai ntawm lub zog hloov hluav taws xob kuj raug kuaj pom thiab xa mus rau lub khoos phis tawj sab saud. Nyob rau tib lub sijhawm, qee qhov kev tswj hwm qhov hloov pauv ntawm lub khoos phis tawj sab saud kuj tseem tuaj yeem tswj hwm los ntawm microcomputer system los tswj cov zis hluav taws xob thiab tam sim no ntawm kev hloov hluav taws xob. Kab lus no siv PIC microcontroller raws li cov kev taw qhia ntse tswj Circuit Court thiab lub ntsiab Circuit Court ntawm lub zog hloov hluav taws xob los ua haujlwm. Lub inverter Circuit Court nyob rau hauv lub ntsiab Circuit Court ntawm ib tug loj muaj peev xwm hloov fais fab mov feem ntau yog ib tug H- choj qauv, uas muaj peev xwm txais yuav ib tug nyuaj switching los yog mos switching txoj kev. Ob txoj kev yog dav siv nyob rau hauv loj muaj peev xwm hloov fais fab mov txawv teb chaws. Txhawm rau ua kom yooj yim ntawm cov qauv hauv Circuit Court thiab cov txheej txheem tsim khoom, lub zog hloov tshuab tau txais yuav hauv cov khoom siv hluav taws xob no. Txawm li cas los xij, qhov kev poob qis ntawm cov keyboards nyuaj yog ntau dua li cov keyboards mos, yog li nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov khoom siv hloov pauv nrog cov zaus ua haujlwm qis dua thiab poob qhov tsim nyog. Yog tias tus qauv tsim tsim nyog, lub zog hloov tshuab tseem muaj qhov tseem ceeb heev. Vim yog txoj kev tswj kom paub tab, cov qauv tseem ceeb hauv Circuit Court, thiab cov thev naus laus zis feem ntau siv los hloov cov khoom siv hluav taws xob, kab lus no tsuas yog qhia ntau yam tshiab hauv kev tsim cov peev txheej loj hloov hluav taws xob: PFC thev naus laus zis, kev ua haujlwm ruaj khov, thiab ntau lub zog sib npaug tam sim no sib koom.
