The Simulation of Three-Phase Voltage Source PWM Rectifier

Yajing Gao, Junqiang Li, Haifeng Liang

Open publisher page 3 citations

Abstract

Three-phase PWM voltage rectifier (VSR) applies Pulse Width Modulation (PWM) technology, it can overcomes the drawbacks of the conventional rectifiers, and has higher power factor, lower harmonic current and rapid dynamic respond, so VSR used widespread. In this paper a dual-channel closed-loop control strategy with current-inner-loop and voltage-outer-loop is adopted for VSR, which makes the DC-side voltage remain steady and the system will run in unit factor. A simulation model of VSR is established, proper parameters are selected, and the control result is fine.
