Lub npe hu ua silicon controlled rectifier, qhov tseeb, yog ib hom kev tswj fais fab hluav taws xob raws li lub zog hluav taws xob hluav taws xob cov khoom siv hluav taws xob thiab cov ntse digital tswj Circuit Court ua lub hauv paus. DC fais fab mov ntawm cov cuab yeej rub no siv DC voltage ntawm thyristor rectifier los muab lub zog rau lub hoisting motor. Lub armature thiab magnetic teb ntawm lub cev muaj zog tuaj yeem siv los ntawm thyristor rectifier, vim tias DC voltage ntawm lub rectifier tuaj yeem hloov kho tsis tu ncua los ntawm qhov ua kom ncua lub kaum sab xis, thiab qhov ceev ntawm lub cev muaj zog tuaj yeem hloov pauv kom ua tiav cov kev cai nrawm nrawm.
Nws yog tus cwj pwm los ntawm kev txuag hluav taws xob, thiab muaj ntau yam zoo xws li kev ua haujlwm siab, tsis muaj suab nrov thiab hnav, cov lus teb ceev ceev, me me, lub teeb yuag, thiab lwm yam. Nws yog thawj qhov kev xaiv thiab tsim nyog cov khoom siv fais fab rau cov tuam txhab tsim khoom. txheej txheem.
