基于改进开关矢量表的三相电压型PWM整流器
Three-phase Voltage Source PWM Rectifier Based on Improved Switching-vector-table
摘要
Abstract
In order to improve the dynamic characteristics of the DPC(the abbreviation of direct power control) method used in three-phase voltage source PWM(the abbreviation of pulse-width modulation)rectifier,an improved 18 sectors switching-vector-table according to the mathematical model of three-phase voltage source PWM rectifier DPC system and the model of 18 sectors switching-vector-table,on the basis of analyzing the instantaneous value of DC side voltage was proposed. The new switching-vector-table could make a better dynamic performance by effectively controlling the system no matter the DC side voltage was instable or suffered a large disturbance. Simulation and experiment had been carried out by building a DPC system. It indicates that the DPC system with improved switching vector table has a better performance in steady state.关键词
