Abstract:
A frequency regulator protection circuit for controlling the acceleration of an electric vehicle, comprisinga power unit; a display unit connected to the power unit and displaying a plurality of IC power sources; a protection unit connected to a motor and to the power unit to be supplied with power; a control unit connected to the motor and to the data processor unit, the control unit receiving a signal of rotation speed from the motor; a sensor unit connected to the control unit, the sensor unit detecting a current overload and outputting a corresponding overload signal; a data processor unit comprised of a delay circuit, a frequency change control circuit, and a vibration circuit, the data processor unit receiving the overload signal from the sensor unit and outputting a corresponding frequency change signal; a trigger unit connected to the data processor unit to receive the frequency change signal, and outputting a first regulation signal; an output unit receiving inputted signals indicating an insufficiency of pedal control, brake control, over-speed control, or motor overload control, and outputting a corresponding second regulation signal; and a regulator unit connected to the trigger unit and the output unit to receive the first and second regulation signals and consequently achieves a corresponding power cutoff to provide an adequate power for motor starting or slope climbing.
