【Abstract】 This paper discusses the current commutation of the bi directional switches in a matrix converter. On the basis of analyzing several current commutation methods,semi soft commutation algorithm implemented by the CPLD is proposed. The simulation and experiment results demonstrate the feasibility and reliability of this scheme.更多还原
