Voltage Spikes and Harmonics Reduction for Inductive Load Single Phase Matrix Converter Using MATLAB

This work presents improved sinusoidal pulse width modulation (ISPWM) used for reduction of harmonics from the output of cycloconverter based on single-phase matrix converter (SPMC). The usage of inductive load often arise the problem of switching spikes which can be overcome by providing a commutation path for energy stored at the load. The insulated gate bipolar transistor (IGBT) was used as the switching device. The modeling and simulation of the work were implemented by MATALAB/SimuLink. Simulation results for different desired output frequencies are presented showing how to cancel the spikes generated by the inductive load. The paper presents also the way to reduce the harmonics using the proposed improved sinusoidal pulse width modulation (ISPWM) and comparison with traditional sinusoidal pulse width modulation (SPWM).
