摘要
为了解决直流电机转向及速度控制问题,设计了一种H桥驱动电路。以IRF530为开关元件、IR2110为栅极驱动芯片,由DSP产生PWM信号,经过光耦隔离和逻辑电路后送至IR2110进行控制。给出了整体驱动控制电路、上下桥臂的栅源电压波形、上桥臂的浮动电压信号以及电机两端的运行电压信号。测试分析表明,该方案很好地实现了电机的正反转控制及电机速度调节,电机运行平稳,达到了设计要求,对直流电机控制应用具有较高的参考价值。
One of H-bridge driving circuit is designed ibr resolving swerve and speed control problem of DC motor. It＇s based on IRF530 for switch element, IR2110 for Grid driver chip, DSP for producing PWM signal. The wave form is giving that of the grid source voltage of up and down the bridge arm, and floating voltage signal of up bridge arm, and the motor running voltage signal. Through tests and analyses, it shows that the motor runs smoothly, and implementes the aim of control swerve and speed of DC motor. Finally, the important note is given.
