电压型PWM整流器控制现状及发展趋势分析

Analysis of Control Status and Development Trend of Voltage Source PWM Rectifier

针对微电网及工业领域中目前广泛应用的电压型PWM整流器,首先对其主要原理、双闭环控制结构进行了简要分析,按被控量类型将控制系统分为电流和功率两大类,在此基础上全面阐述了传统、现代及智能控制等方法,最后展望了电压型PWM整流器控制的发展趋势。

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.
