Abstract: A motor controller with a reverse-bias preventing mechanism includes a pre-charging unit, a protection unit, a conversion unit and a control unit. The pre-charging unit receives a power signal through a first electric-conduction path, and converts the power signal into a pre-charging signal according to a control signal. The protection unit receives the power signal through a second electric-conduction path, and determines whether to output the power signal, according to the polarity of the power signal. The conversion unit, coupled to the protection unit, receives the power signal outputted by the protection unit, and converts the power signal into a work voltage. The control unit, coupled to the conversion unit and the pre-charging unit, receives the work voltage to generate the control signal. The current of the power signal flowing through second electric-conduction path is smaller than the current flowing through first electric-conduction path.

Abstract: A motor control method for coupled an electronic vehicle is provided. The motor controller controls a motor and is powered by a battery. The motor control method includes: when a main relay of the motor controller suddenly breaks contact, in a first phase, feeding back a surge current into the battery to suppress the surge current by a diode and a first current limit resistor of a first protecting circuit of the motor controller; and, in a second phase, conducting a discharge switch of a second protecting circuit of the motor controller by a control unit of the motor controller, and releasing the surge current to a reference voltage range by the discharge switch and a second current limit resistor of the second protecting circuit.
