CONTROL DEVICE FOR DRIVING SPECIAL LOAD OF VEHICLE AND THE CONTROLMETHOD THEREFOR

A control device for driving an external load which receives DC voltage from an energy supply unit of a vehicle and converts the DC voltage into AC voltage to supply voltage to a load outside the vehicle, according to one embodiment of the present disclosure, includes: a DC/AC output inverter that converts the received DC voltage into the AC voltage and outputs the converted AC voltage by switching of a switching element; a current sensor that senses an inductor current value of an output terminal of the DC/AC output inverter; a microcontroller that receives the sensed current value and outputs a pulse width modulation control signal input to the switching element of the DC/AC output inverter; a gate drive that receives the pulse width modulation control signal output from the microcontroller and outputs a gate driving signal to a gate of the switching element; and a comparator that compares the current value sensed by the current sensor with a preset reference current value and outputs a disable signal to forcibly stop outputting the gate driving signal when the sensed current value is not within the preset reference current value range.
