Niaj hnub no peb coj koj mus paub yuav ua li cas tam sim no ntawm lub transformer yog loaded.
1. Qhov tseeb load tam sim no ntsuas ntawm qhov sib npaug hauv cov chav nyob yog tswj los ntawm kev kho PWM ntxiv. Ob peb chav nrog Synchronous PWM yog ua nyob rau hauv parallel, thiab cov circulating tam sim no raug tshem tawm los ntawm ntxiv PWM tswj. Txhua chav tsev yooj yim siv hluav taws xob sib cais. Txhua chav tsev yooj yim muaj nws tus kheej tswj los muab lub zog rau lub nra los ntawm insulated windings.
2. PWM yog ib qho kev ywj pheej, asynchronous thiab dawb khiav teeb liab, thiab txhua chav tsev muaj nws tus kheej sib txuas DC. Ntawm daim phiaj sab, txhua chav tsev yooj yim muaj nws tus kheej sinusoidal LC lim. Yog hais tias cov zis tawm kuj yog hluav taws xob cais, tsis muaj circulating tam sim no ntawm txawv DC txuas.
3. Qhov no yog txoj hauv kev yooj yim tshaj plaws los txuas cov txheej txheem ywj pheej yooj yim nrog cov txheej txheem ywj pheej tswj nyob rau hauv parallel. Ib qho yooj yim tsim raws li lub tshuab hluav taws xob sab hluav taws xob cais tawm yog qhia. Peb ywj siab 4-quadrant drives nrog discrete motor windings nyob rau hauv parallel. Lub tsav tuaj yeem ua haujlwm nyob rau hauv parallel nrog ib lossis ob lub tsav.
