交流电机正反转电路的实现需要使用交流电电源、电动机及电子元器件等。交流电机的正反转需要保证两个问题：

1.要在实现正逆转的同时保证电流不会超过电机的额定电流;

2.要保证电动机正反转时的电压和频率都能满足其额定数值。

因此需要选用交流变频器来实现对电机的正反转控制。

具体实现方法为：通过PWM控制交流电源电压的正负和大小，例如，当需要实现正转时，控制器向电机提供正向的三相电流，当需要实现反转时，控制器向电机提供相反的三相电流。另外，也可以通过继电器或接触器的控制来实现正反转。

输入交流电源的电压通过变频器进行控制，并输出为三相交流电流，控制变频器的输入信号可以是控制器的PWM信号或是通过继电器或接触器的控制信号。

在控制器中，该电路可以使用单片机或者PLC来实现，通过编程来实现正反转的控制逻辑，并将输出信号传递给变频器，来控制电机的正反转。
