Simulation research on direct power control system of three phase boost type PWM rectifier
Author(s): 
Pages: 4-7
Year: Issue:  6
Journal: Machine Tool Electric Apparatus

Keyword:  PWM整流直接功率控制瞬时功率单位功率因数;
Abstract: 基于三相PWM整流器的矢量控制原理,建立了整流器所需的功率控制模型,根据功率控制数学模型,详细分析了基于直接功率控制策略的三相电压型PWM整流器控制系统的组成与原理.在Matlab/Simulink环境下,搭建了直接功率控制系统的仿真模型,并与传统的采用电压电流双闭环控制策略的控制系统进行比较.仿真结果表明,DPC系统具有更好的动,静态特性,并且结构简单,无需PWM调制模块,高功率因数等优点.
