Regulated power supply 現畫is a kind of electronic equip文風ment that can provide stab間舊le AC or DC power supply for load, tha去草t is to say, it can be d錯人ivided into two categories, DC r可大egulated power supply and AC r見體egulated power supply. This p做老aper will focus on the int費又roduction of DC regulated po街分wer supply. Next, I will introduc制問e the classification of 河吃DC regulated power supply and t內生he design of two kinds of DC regul票嗎ated power supply.



The working mode of DC regulated power區些 supply is mainly divided into thr房都ee points



1. Controlled rectifier type is裡紅 to adjust the output voltage by 銀機changing the turn-on tim影音e of thyristor.



2. Chopper type, the input is uns懂自table DC voltage, to change the on-o下身ff ratio of the switch circuit to 做信obtain unidirectional pulsati這一ng DC, and to obtain stable DC費西 voltage after filtering.



3. For the converter type, t長行he unstable DC voltage 雜土should be transformed into high 長西frequency AC through t司麗he inverter, and the 知湖new DC output voltage can be視窗 obtained after the 樂門voltage transformation r湖志ectification filtering, and f紅金ed back to the control inve嗎票rter working frequen錯年cy, so as to achieve the pu玩要rpose of stabilizing the output DC vol北時tage.
