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.
