摘要：

Brief introduction to digital commutation strategy of matrix converter is given and requirement to commutation techniques under condition of power integration is stated. Then, flaw of existing full-digital voltage commutation method is pointed out after the change of the critical area which switch sequence will encounter corresponding to the variety of displacement angle at the input-side of converter has been explicated, then several rules have been presented and used to instruct detailed voltage commutation method built. Increment of switches' commutation-times, thanks to the new method employed, is analyzed in succession. An experimental prototype which employed full-digital four-step commutation strategy is established to further verify the mentioned method.
