摘要
脉宽调制(PWM)整流器作为一种重要的治理谐波污染方法,能从源头上消除谐波并提高功率因数。这里针对电流型PWM整流器,进行了原理分析,介绍了控制方法及调制方式,设计了一台3 kW原理样机,结合具体电路参数,得出网侧滤波器参数与直流侧电流大小和功率因数的关系,并利用Matlab仿真及实验进行验证。
Pulse width modulation （PWM） rectifier as one of the important management methods, can effectively eliminate the harmonic pollution and improve power factor at the beginning.The working principle of current source PWM rectifier is analyzed ,the control strategy is introduced and the modulation scheme is illustrated.A prototype of 3 kW is designed.A precise relationship is developed between the parameters of the source filter and output current as well as power factor based on the parameters of the prototype.Simulation results using Maflab and experiment are presented to validate the experiment.
