摘　　要：Cuk型三相PWM整流电路利用SVPWM调制中的零矢量时间作为上下桥臂的直通时间,构成等效Cuk电路中的IGBT导通时间。通过对比分析直通时间占零矢量时间的比例对电路的影响,选择了一种最佳的直通时间占比。采用NI公司的CompactRIO控制器搭建试验平台进行试验验证,结果与理论分析一致,验证了理论分析的正确性和有效性。The cuk-type three-phase PWM rectifier circuit uses the zero vector time in SVPWM modulation as the shootthrough time of its upper and lower arms to constitute the IGBT conducting time in the equivalent Cuk circuit.By comparing and analyzing the influence of the ratio of the shoot-through time to the zero vector time on the circuit,an optimal proportion of the shoot-through time is selected.The test platform is built by using NI CompactRIO controller.The test results are consistent with the theoretical analysis results,which verifies the correctness and validity of the theoretical analysis.
