摘要：

Aiming at safe commutation and improving quality of output waveforms, the paper presents a new varying-step safe commutation strategy of matrix converter by analyzing the character of traditional four-step commutation and improved four-step commutation strategy. With the input-voltage-based commutation this new strategy synthetically considers the magnitude of input voltage and output current direction and accordingly distinguishes the safe and the unsafe partition. Then different commutation strategies adopted in different partition which improving the reliability of commutation and decreasing the commutation time to improve the quality of output waveform. Finally, experimental results demonstrate the availability and reliability of varying-step commutation strategy of matrix converter.
