High performance intelligent power module for PWM rectifier application

摘要

With the development of power electronics, there are more and more inductive load in power system and the pulse current result by inductive load will bring bad effect to the quality of the grid; On the other hand,when motor of load worked as a generator, the generated energy will be waste.Pulse width modulation(PWM) rectifier have a good performance in this circuit,which can make the input current work at sinusoidal state and improve the power factor; This paper showed the method how to design the PWM rectifier by using intelligent power module(IPM),which including topology selection,control method and power module selection,power losses calculation and prototype testing.At last,some pictures of testing waveform are given.
