Cov muaj pes tsawg leeg thiab kev ua haujlwm ntawm lub zog qis semiconductor DC stabilized fais fab mov system
Feem ntau siv hluav taws xob qis semiconductor DC stabilized fais fab mov system muaj plaub ntu: fais fab transformer, rectifier circuit, lim circuit thiab voltage stabilizer circuit. Daim duab 9-1 qhia nws lub hauv paus ntsiab lus thaiv daim duab thiab tso zis waveforms ntawm txhua feem.
Kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom ntawm DC tswj fais fab mov:
(1) Fais fab transformer: Muab AC voltage ntawm tus nqi yuav tsum tau rau cov khoom siv hluav taws xob. AC voltage muab los ntawm kab sib chaws feem ntau yog 220v (los yog 380v), thiab qhov thib ob coil voltage u2 yog tsawg, uas tuaj yeem txo qhov kev xav tau ntawm cov khoom siv hluav taws xob rau cov khoom siv hauv kev kho, lim thiab voltage stabilization circuits, yog li nws yog qhov yuav tsum tau ua. siv lub transformer los hloov daim phiaj voltage mus rau tag nrho Cov alternating voltage ntawm tus nqi xav tau.
(2) Rectifier Circuit Court: hloov alternating tam sim no mus rau tam sim no ncaj qha. Siv cov khoom siv nrog unidirectional conductivity (xws li diodes thiab thyristors), alternating zoo thiab tsis zoo sinusoidal AC voltage u2 tso zis los ntawm lub transformer yog rectified thiab hloov mus rau hauv ib tug unidirectional pulsating DC voltage D3.
(3) Lim Circuit Court: Hloov cov tam sim no rectified nrog cov pulsation loj rau hauv qhov ncaj ncaj tam sim no. Feem ntau, lub zog cia khoom xws li capacitors thiab inductors yog siv los lim tawm cov khoom sib haum xeeb hauv unidirectional pulsating voltage u3.
(4) Voltage stabilization Circuit Court: kov yeej qhov kev hloov pauv ntawm cov zis hluav taws xob los ntawm kev hloov pauv ntawm daim phiaj hluav taws xob lossis kev thauj khoom tam sim no, thiab tswj xyuas qhov ruaj khov ntawm cov zis hluav taws xob.
