摘要
介绍了无位置传感器的无刷直流(BLDC)电动机反电势过零点控制信号的获取。驱动电路采用三相全桥逆变电路以及MOSFET驱动电路,实现了电机的PWM控制。仿真实验表明,系统能够满足电动助力转向系统对稳定性和跟随性的要求。
The acquisition of counter-potential zero-crossing signals of the BLDC motor is introduced in detail.Three-phase full-bridge inverter and MOSFET driver are used to realize the PWM control for the motor.Simulation experiments show that the system can meet requirements of the power steering system.
