摘　　要：针对传统三相电压型PWM整流器无法输出宽范围直流电压的问题,分析了传统三相电压型PWM整流器与Cuk电路相结合的三相升—降压PWM整流器的工作原理。采用电压电流双闭环控制策略进行控制。最后通过Matlab/simulink进行验证,证明三相升—降压PWM整流器拓宽了输出直流电压的范围。To overcome the disadvantages of traditional three-phase voltage-type PWM rectifier which can not output DC voltage in a wide range, the working principle of a three-phase step-up/down rectifier, which is based on traditional three-phase voltage-type PWM rectifier and C＇uk DC/DC converter, is analyzed. The controller uses the voltage and current double closed-loop control structure. The results of Matlab/simulink confirm that the three-phase step-up/down rectifier can output DC voltage in a wide range.
