Simulation And Application Of Three-Phase Sparse Matrix Converter

Traditional Matrix converter is very simple in structure and has powerful controllability. However it can not be widely used in industry because of commutation problem, low voltage transformation ratio and complicated PWM method. This paper details a novel matrix topology—Sparse Matrix Converter, it compares to matrix converter has the same advantages such as: four quadrant operation; no DC capacitor and high quality input voltage/output current waveforms and more advantages: the number of switches can be reduced; the switches at the line side can turn on and turn off at zero current and need no complex commutation problem. This paper presents basic theory of Sparse Matrix Converter, controlling method and zero current commutation; Lastly, this paper provide the simulink waveforms based on SIMULINK. Simulation models are good tools for the modulation and the experiment system is beneficial to the Sparse Matrix Converter's apply.
