Abstract :
Traditional voltage-controlled commutation strategies are basically proposed to avoid detecting zero crossing problem of current-controlled commutation. Commutation problem is one reason of matrix converter can not be used in high-power environment. This paper proposes a novel four-step safe commutation strategy in transition intervals. The strategy resolves the short circuit phenomenon during changing intervals and consummates the voltage-controlled commutation. It has many advantages such as little influence on input and output waveform, easy to realize and decrease switching loss. Experimental results verify the validity and feasibility of the safe commutation strategies. This commutation strategy possesses a broad application foreground on AC-AC converter.
