Abstract: Researched the hybrid drive technology which based on the three-phase bridge inverter for the brushless DC motor(BLDCM)and the H-bridge inverter for the brush DC motor by making full use the resources of complex programmable logic devices(CPLD).It gave the overall design,different chopper ways and forward/reverse switch methods.Simulation results show that the hybrid driver has a character of high integration,and it can eliminate the competition adventure of the combination logics,and owns several functions,such as the fault protection,the choice of control ways,the embargo of logic,and so on.
