Lub hom phiaj tseem ceeb ntawm cov tus kws kho mob hauv Circuit Court

Tswj kev kho kom raug

Kev siv yooj yim tshaj plaws ntawm thyristors zoo ib yam yog tswj kev kho. Tus paub diode rectifier Circuit Court yog qhov Circuit Court tswj tsis tau. Yog tias lub diode raug hloov los ntawm thyristor, nws tuaj yeem tsim cov khoom siv hluav taws xob tswj hluav taws xob, inverter, kev tswj lub cev muaj zog, kev ua kom lub cev muaj zog, tsis hloov pauv thiab tsis siv neeg tswj. Hauv kev tsim hluav taws xob, ib nrab ntawm kev hloov pauv tam sim no feem ntau tau teeb tsa raws li 180 °, uas yog hu ua hluav taws xob kaum. Ua li no, hauv txhua qhov kev ua haujlwm ib nrab ntawm U2, lub kaum hluav taws xob tau ntsib los ntawm tus nqi xoom mus rau lub sijhawm ntawm lub plawv dhia hu ua tswj lub kaum ntse ntse α; lub kaum ntse ntse hluav taws xob uas lub thyristor ua nyob rau hauv txhua qhov zoo ib nrab ntawm lub voj voog hu ua conduction angle θ. Pom tseeb, ob qho α thiab θ tau siv los qhia qhov kev coj lossis thaiv ntau yam ntawm cov thyristor thaum lub sijhawm ib nrab ntawm lub vojvoog tom ntej. Los ntawm kev hloov pauv lub kaum ntse ntse α lossis lub kaum ntse ntse θ, qhov nruab nrab tus nqi UL ntawm cov mem tes DC qhov hluav taws xob ntawm qhov hloov pauv tau hloov pauv, thiab kev tswj xyuas qhov tseeb tau ua tiav.

Hloov tsis tau

Kev ua haujlwm ntawm thyristor tsis yog tsuas yog kho kom raug, nws kuj tseem tuaj yeem siv ua qhov hloov pauv tsis sib xws kom qhib sai lossis tawm ntawm Circuit Court, paub qhov hloov pauv ntawm qhov ncaj qha tam sim no mus rau qhov hloov pauv tam sim no, thiab hloov ib zaus ntawm qhov hloov pauv tam sim no mus rau lwm zaus ntawm kev hloov pauv. tam sim no, thiab ntau ntxiv.
