Research on Three-phase PWM Rectifier Based on Voltage Space Vector

Wang Bu-gen

Abstract

Three-phase pulse width modulation(PWM) rectifier is widely researched and applied due to achieve higher power factor.The mathematical model of three-phase PWM rectifier is analysed including three-phase static coordinate and two-phase synchronous rotation coordinate respectively.The control strategy based on voltage space sector and phase-locked technology are also introduced.Finally a 20 kVA three-phase PWM rectifier using TMS320F2812 digital controller based on voltage space sector technology is built.Experimental results verify the PWM rectifier has a good performance.
