Modeling and dynamic analysis of a fast response three phase PWM voltage source rectifier

Abstract

This paper presents dynamic analysis of a three-phase PWM voltage source rectifier based AC/DC power supply system using a feedforward/feedback control algorithm proposed by the authors previously. A small signal model of the power supply in s-domain is derived. This model is used in obtaining transfer functions describing the response of the DC output voltage following load, line and reference changes. The dynamic analysis is verified by transfer function simulation using MATLAB and time domain simulation of the power supply system.
