Abstract:
For the voltage source PWM rectifiers which are increasingly widely used in micro-grids and many industrial fields, the main principles and double closed-loop control structure of the voltage source PWM rectifiers are briefly analyzed. According to the type of controlled quantity, the control system is divided into two categories including current and power, then the traditional, modern and intelligent control methods are comprehensively expounded based on the strategy. Finally the development trend of voltage source PWM rectifier control is expected in the paper.
