Seb yuav xaiv theem-hloov tswj lossis xoom-hloov tswj thaum lubtswj fais fabua haujlwm yuav tsum tau txiav txim siab raws li qhov tshwj xeeb daim ntawv thov scenario.Zero-crossing tswj yog hais txog kev xa cov khoom thauj khoom hloov pauv txhua zaus lub zog hluav taws xob hluav taws xob dhau los ntawm xoom point, thiab tswj cov khoom siv hluav taws xob los ntawm kev kho qhov ntev ntawm lub sijhawm ua haujlwm.Txoj kev tswj hwm no muaj txiaj ntsig zoo dua thaum lub thauj khoom yog linear impedance, thiab tuaj yeem ua tiav lub zog ntau dua.Phase-hloov tswj yog hais txog kev xa cov khoom thauj mus los ntawm cov theem sib txawv ntawm cov khoom siv hluav taws xob, thiab tswj cov khoom siv hluav taws xob los ntawm kev kho qhov ntev ntawm lub sijhawm ua haujlwm.Txoj kev tswj no yog tsim rau cov ntaub ntawv uas lub load yog nonlinear impedance (xws li kev tswj ceev ntawm lub cev muaj zog), thiab tuaj yeem paub txog kev hloov kho ntawm cov load voltage thiab tam sim no, tsis txhob overload thiab chopping.Yog li ntawd, seb puas yuav xaiv theem-hloov tswj lossis xoom-hloov tswj thaum ua haujlwm yuav tsum tau xaiv raws li qhov xwm txheej tiag tiag.Yog hais tias lub load yog ib tug linear impedance thiab yuav tsum tau ib tug high-power factor, zero-hla tswj yuav xaiv tau;Yog hais tias lub load yog nonlinear impedance, thiab lub load voltage thiab tam sim no yuav tsum tau kho smoothly, theem-hloov tswj yuav raug xaiv.
Nws yuav tsum tau muab sau tseg tias thaum siv xoom-hloov tswj, tus cab kuj hloov khoom siv yuav tsum tau synchronized nrog rau xoom point ntawm lub hwj chim mov voltage kom tsis txhob muaj teeb meem xws li voltage hla thiab dhau tam sim no peaks.Yog li ntawd, nws yog feem ntau yuav tsum tau siv lub siab synchronization trigger kom tiav cov txheej txheem no.
Xaiv theem-hloov lossis xoom-hloov hom thaum xaivscr zog regulatorfeem ntau nyob ntawm koj qhov load thiab seb koj lub rhaub yuav ua haujlwm li cas.Yog tias koj muaj lus nug txog qhov no, hu rau Noker Electric ncaj qha, peb yuav muab cov kev daws teeb meem zoo tshaj rau koj.
