【Abstract】 The key one of the technologies in devising the matrix converter sample is making the four-quadrant switches commutating safely.In this text the Four-Step commutation logical circuit is completed,by using the ispLSI1032E-70L (In-System Programming Logic Device)which be manufactured in Lattice Company,based on introducing the four-step commutation top structure and working theory.Under the Synario environment simulation and sample experiment results are presented to verify the validity of the proposed method.更多还原
