摘要
根据三相电流型PWM整流器的运行特性,给出了整流器开关函数的定义。并针对三相电流型整流器的高频数学模型,将电压型整流器SPWM调制的二逻辑信号转化为电流型整流器SPWM调制的三逻辑信号,不但实现了电流型整流器交流侧的单位功率因数,而且获得了直流侧的平稳运行,仿真结果及实验波形证实了上述结论。
According to operation performance of 3-phase current source rectifier, a novel definition of switch function is proposed, and with mathematical model of 3-phase cun＇ent rectifier, the tri-logic SPWM of current rectifier is obtained by hi-logic SPWM of the voltage rectifier, the unity power factor correction of current rectifier has been carried out, the result is verified by computer simulation and experiment.
