Modeling and Simulation of Matrix Converter Using Space Vector PWM Technique

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 has following advantages over conventional converters with low volume, sinusoidal input current, bidirectional power flow, minimizing of lower order harmonics 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 two different modulation techniques such as PWM and SVPWM. The basic principle and switching sequence of these modulation techniques are presented in this paper. The output voltage, output current waveforms and THD spectrum of switching waveforms connected to RL load are analyzed by using Matlab/Simulink software. The simulated results are analyzed and show that the THD is better for SVPWM technique
