摘　　要：充分利用可编程逻辑器件(CPLD)资源,研究了基于三相桥逆变器的无刷直流电动机(BLDCM)和基于H桥逆变器的有刷直流电动机的混合驱动技术,给出了总体设计、不同斩波方式及正、反转切换方法。仿真结果证明,混合驱动器集成度高,可消除组合逻辑竞争冒险,具有故障保护、控制方式选择和逻辑封锁等多种功能。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.
