摘　　要：该文对三相交流电进行整流,以直流电机为负载,进行Matlab仿真并对电路中的电抗参数进行计算。使用了电网侧线电压作为载波对晶闸管进行双脉冲触发,且晶闸管触发角可以依据负载的电压实时进行调节。该文还对电机转子串电阻启动的参数进行计算、电路模型搭建、仿真。该文还介绍Matlab中Powergui的使用说明,并阐述一些电流谐波治理方案。The paper takes rectification of three phase power as DC motor source,and computes the reactance in the circuit and simulation through the Matlab.Taking double pulses and its carrier wave＇s frequency is taking from the power lines triggers the thyristor.Meanwhile,regulating the trigger angle of thyristor can adjust the output voltage of circuit dynamically.The paper also calculates the stepping resister and constructs the simulation circuit.The result of simulation can proves the design of circuit and its parameters is right and suitable.At the final of paper,introducing Powergui module in the Matlab and advances two theoretic measures to manage the current harmonics.
