Abstract
A vehicle charger includes a power supply device, a communication module, a reference changing unit, a compensator, a controller, and a gate driver. The power supply device changes an input voltage into a voltage required to charge a portable device and outputs the changed voltage. The communication module receives information on at least one of a voltage and a current, which are required to charge the portable device. The reference changing unit generates at least one of a reference voltage and a reference current based on the information on the at least one of the voltage and the current. The compensator generates a compensation signal based on a result obtained by comparing the at least one of the reference voltage and the reference current with at least one of a sensed voltage and a sensed current, which are obtained by sensing at least one of an output voltage of the power supply device and a current supplied from the power supply device to the portable device. The controller generates a gate driving signal according to the compensation signal. The gate driver generates a gate voltage for controlling switching operation of the power supply device according to the gate driving signal.
