The output wave shape is obtained based on the single-phase matrix converter principle. Reasons of the output wave shape distortion are analyzed. The improving methods and the improving circuit diagram are proposed. Finally the output wave shape of single-phase matrix converter ideal is obtained by the simulink modeling simulation. It is shown that the AC-AC converter has good features such as unlimited output frequency, input and output electrical current approach sine wave etc. With good developing foreground, it deserves further researching.
