Dab tsi yog cov khoom ntawm DC tswj fais fab mov?
Qhov muaj pes tsawg leeg ntawm DC tswj fais fab mov
DC stabilized fais fab mov feem ntau yog tsim los ntawm plaub qhov chaw: fais fab transformer, rectifier circuit, lim circuit thiab voltage stabilizer circuit.
1. Fais fab transformer
Fais fab transformer yog ib hom mos sib nqus electromagnetic tivthaiv, uas nws lub luag hauj lwm yog lub hwj chim kis tau tus mob, hloov voltage thiab rwb thaiv tsev cais, thiab yog dav siv nyob rau hauv lub hwj chim mov technology thiab hluav taws xob electronics technology.
2. Rectifier Circuit Court
A "rectifying circuit" is a circuit that converts alternating current electrical energy into direct current electrical energy. Most rectifier circuits are composed of transformers, rectifier main circuits and filters. It is widely used in DC motor speed regulation, generator excitation regulation, electrolysis, electroplating and other fields. The rectifier circuit usually consists of the main circuit, filter and transformer. After the 1970s, the main circuit is mostly composed of silicon rectifier diodes and thyristors. The filter is connected between the main circuit and the load to filter out the AC components in the pulsating DC voltage. The transformer setting depends on the specific situation. The function of the transformer is to achieve the matching between the AC input voltage and the DC output voltage and the electrical isolation between the AC grid and the rectifier circuit.
Lub luag haujlwm ntawm lub rectifier Circuit Court yog hloov pauv tam sim no nrog qis voltage tso zis los ntawm AC kauj ruam -down circuit rau hauv ib qho - txoj kev pulsating direct tam sim no, uas yog cov txheej txheem rectification ntawm alternating tam sim no. Rectifier Circuit Court yog tsim los ntawm rectifier diodes. Qhov hluav taws xob tom qab dhau los ntawm lub voj voog rectifier tsis yog AC voltage, tab sis ib qho hluav taws xob sib xyaw uas muaj DC voltage thiab AC voltage. Nws yog kev cai hu ua unidirectional pulsating DC voltage.
3. Lim Circuit Court
Lub lim dej feem ntau yog siv los lim cov ripple hauv cov zis hluav taws xob rectified, thiab feem ntau yog tsim los ntawm cov khoom siv reactive, xws li lub capacitor C nyob rau hauv parallel nrog lub load kuj, los yog inductor L nyob rau hauv series nrog lub load, thiab ntau yam complexes tsim. ntawm capacitor thiab inductors. lim Circuit Court.
4. Regulator Circuit Court
Lub tshuab hluav taws xob tswj hluav taws xob yog hais txog ib lub voj voog uas tuaj yeem ua kom cov zis hluav taws xob tsis tu ncua thaum qhov hluav taws xob input, load, ambient kub, Circuit Court tsis, thiab lwm yam. Qhov Circuit Court no tuaj yeem muab DC lub zog ruaj khov thiab siv dav hauv ntau yam khoom siv hluav taws xob.
