PURPOSE: An apparatus and a method are provided to achieve improved stability and reliability by feedback detecting the voltage of DC link between the generator and battery and compensating the torque and speed of the motor and engine. CONSTITUTION: An apparatus comprises a main control unit(100) for controlling the speed and torque of an engine and a motor(400) and controlling generated energy by feedback detecting the voltage of DC link; a gate driver(200) for generating a PWM switching signal in accordance with the control signal applied from the main control unit; and an inverter(210) for driving the motor by converting the voltage applied from a battery or generator into a three-phase AC voltage in accordance with the PWM switching signal generated from the gate driver, converting the AC current generated from the motor into a DC current, and supplying the DC current to the battery.
