It provides modern hi-tech for industrial production, transportation, office automation, family, so widely used.Three-phase controlled rectifier circuit controlled rectifier circuit of single-phase relative to its output voltage dc, the main function : through resistive loads of electric circuit and perceptual load simulation to realize the circuit. When need to change control function, as long as modifiy the related parameters of the simulation circuit.This paper is to realize the control of electric motor with simulink. AC becomes DC. One is under resistive loads of output voltage waveform, One is under inductive load of output voltage waveform, triggering pulse Angle and resistance of three-phase all control the inductor rectifier circuit output voltages and currents, and the influence law of components for the practical application of the parameter selection laid a foundation and provides theory.Key words: rectifier circuit; control Angle; conduction; simulink目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc293939973 摘 要 PAGEREF _Toc293939973 \h 1 HYPERLINK \l _Toc293939974 Abstract PAGEREF _Toc293939974 \h 2 HYPERLINK \l _Toc293939975 目 录 PAGEREF _Toc293939975 \h 3 HYPERLINK \l _Toc293939976 前 言 1 HYPERLINK \l _Toc293939977 1 三相桥式全控整流电路的原理 1
