Taug qab kev tswj fais fab mov Circuit Court thiab nws cov yam ntxwv cuam tshuam
Vim tias lub voj nce siab heev, qhov drift vim qhov hloov pauv voltage thiab thauj khoom tam sim no hloov me me heev. Txoj hauv kev los txo qhov kub thiab txias yog xaiv lub tshuab hluav taws xob ua haujlwm uas tsis tshua muaj kev cuam tshuam los ntawm qhov kub thiab txias, xaiv cov resistor nrog cov yeeb yaj kiab hlau lossis hlau winding thiab cov coefficient kub me me, thiab siv lub ntsuas kub-compensated regulator rau siv fais fab mov.
Daim duab kos duab ntawm kev taug qab tswj fais fab mov muaj li ntawm op amp. Yog tias qhov nce ntawm op amp loj txaus, qhov kev sib tw voltage Vos yuav tsawg dua Vs, Vo=Vs(R1 plus R2)/R2, yog li cov zis voltage yog txiav txim los ntawm qhov siv voltage Vs thiab qhov piv ntawm R1 thiab R2. Yog li ntawd, lub drift ntawm lub hwj chim mov yog txiav txim los ntawm qhov kev siv voltage, kev hloov ntawm qhov voltage divider kuj, thiab hais txog.
1000W tsis siv neeg voltage regulation AC tswj fais fab mov Circuit Court
Lub Circuit Court ntawm 1000W tsis siv neeg voltage-regulating AC tswj fais fab mov yog qhia nyob rau hauv daim duab hauv qab no, thiab nws txoj kev ua hauj lwm: T yog tus kheej-coupling voltage regulator. Nws cov zis kawg yog tsau, thiab cov tswv yim kawg yog hloov kho los ntawm servo lub cev muaj zog kom cov zis tas li.
