摘　　要：在电力电子领域中,整流电路尤其是三相整流电路扮演着十分重要的地位。首先通过Simulink环境建立电容型三相不可控桥式整流电路的模型,然后改变电解电容和负载电阻的大小来分析三相整流电路输入功率因数的变化;通过增大电容值,使得谐波增加,输入功率因数变小;最后通过电路实验验证该仿真的正确性。In the field of power electronics,the three-phase rectifier circuit plays a very important role.In this paper,the model of capacitive three-phase uncontrollable bridge rectifier circuit is established by Simulink environment,and then the change of input power factor of three-phase rectifier circuit is analyzed by changing the value of electrolytic capacitance and load resistance.By increasing the capacitance value,the harmonic is increased and the input power factor is reduced.Finally,the correctness of the simulation is verified by circuit experiment.
