A single phase matrix converter for AGPU

This paper designs the single phase matrix converter to obtain a constant 110V/400Hz output, irrespective of the distortions in both the supply and load. The single phase matrix converter employs a safe-commutation strategy, which results in the elimination of voltage spikes on switches, without the need of a snubber circuit. This is facilitated through proper switching control algorithm. Also, an improved control structure for the matrix converter system is devised in the simulation to control the output voltage. The operating principles of this converter are described and the circuit behaviour is confirmed by the MATLAB/Simulink simulation results.
