Verification of Three Phase Full Wave Controlled Rectifier using MATLAB Simulation Model

Abstract

In this paper, the modeling and implements of a three phase full wave controlled rectifier has been modeled on MATLAB SIMULINK software version 7.10.0.449[R2010a]. It is also deals with the simulation analysis of three phase full wave controlled rectifier by obtaining various waveforms. For large power dc loads, three phase ac to dc converters are commonly used. Three phase half wave converter is rarely used because it introduces dc component in the supply current. Some years back ac to dc power conversion was achieved using motor generator sets, mercury arc rectifiers, and thyratorn tubes. The modern ac to dc power converters are designed using high power, high current thyristors and presently most of the ac-dc power converters are thyristorised power converters. This paper also presents that how a full wave controller works for different firing angles at a given time and waveforms were obtain for verification.
