摘　　要：在无刷直流电机(BLDC)控制系统中,其关键技术是设计线圈换相控制信号和PWM调压控制信号,这两种信号分别通过各自的驱动元件来控制B L D C的线圈电流方向和电机线圈两端的电压。"控制信号叠加技术"将两种信号叠加,通过一个功率驱动管来实现上述两个功能,这种技术取得了较好的实际应用效果。In BLDCM control system, the coil commutation control signals and PWM control signals are the key technology, the two signals control the current direction of the coil and the voltage across the coil of BLDCM respectively,through each driving elements. ＂Control signal stacking technique＂ makes the two signals superimposed, and then a power drive pipe can achieve the above two functions. This technology has achieved good effect in practical application.
