Comparison of Modulation Techniques for Matrix Converter

J. Karpagam, A. Nirmal Kumar and V. Kumar Chinnaiyan

Abstract—Matrix Converters can directly convert an ac power supply of fixed voltage into an ac voltage of variable amplitude and frequency. Matrix Converter is a single stage converter. The matrix converters can contribute to the realization of low volume, sinusoidal input current, bidirectional power flow and lack of bulky reactive elements. All the reasons lead to the development of matrix converter. Based on the control techniques used in the matrix converter, the performance varies. So this paper analyses the performance of matrix converter with three different modulation techniques such as PWM, SVPWM and SVM. The basic principle and switching sequence of these modulation techniques are presented in this paper. The output voltage, output current waveforms, voltage transfer ratio and THD spectrum of switching waveforms connected to RL load are analyzed by using Matlab/Simulink software. The simulated results are analyzed and shows that the THD is better for SVM technique.

Index Terms—Matrix Converter, Pulse Width Modulation (PWM), Space Vector Pulse Width Modulation (SVPWM),Space Vector Modulation (SVM), Total Harmonic Distortion(THD).
