摘　　要：为了满足步进电机在特殊领域的应用要求,利用分离电路设计一种全桥驱动电路。以IRF520为功率放大器件、IR2103为栅极驱动芯片,通过采样电阻和高精度运算放大器获得步进电机的相电流,从而得到步进电机的电流细分控制。并给出全桥驱动电路,实现步进电机的高精度控制。In order to meet the application requirements of the stepping motor in the specifie field, a full bridge driving circuit was designed by using the discrete circuit. With IRF520 as the power amplifier and IR2103 as the gate drive chip, through the sampling resistor and the high pricision operational amplifier to obtain the phase current of the stepping motor, so as to realize the current micro step control of stepping mo- tor. Presented the full bridge driving circuit, realized the precision control of the steooing motor.
