Modeling and simulation of Single Phase Matrix Converter using PWM

This paper implements Single Phase Matrix Converter (SPMC) in different topologies for various functions such as frequency converter, rectifier, inverter and chopper. A single topology, capable of performing all functions of generalized single phase converter utilizes either AC or DC supply to synthesize the output using Pulse Width Modulation (PWM) techniques. The circuit requires four Common emitter anti-parallel Integrated Gated Bi-polar Transistor (IGBT) with diode pair for bi-directional switching. A safe commutation strategy is facilitated by a switching sequence to avoid voltage spikes on switches. Prior to hardware implementation, simulations were performed to investigate the behavior of SPMC using MATLAB/Simulink.
