1. A method of controlling a charging device for vehicles, comprising:
- sensing, by a controller, overcurrent in a power factor correction circuit of the charging device;
turning off, by the controller, the power factor correction circuit upon sensing overcurrent after the sensing;
increasing, by the controller, an output voltage of the power factor correction circuit when the number of generations of sensed overcurrent is equal to or less than a predetermined first reference value;
turning on, by the controller, the power factor correction circuit after the increasing;
after the turning off of the power factor correction circuit, decreasing, by the controller, power of the power factor correction circuit when the number of generations of overcurrent exceeds the predetermined first reference value and is equal to or less than a predetermined second reference value greater than the first reference value; and
turning on, by the controller, the power factor correction circuit.

Abstract
A method and system of controlling a charging device for vehicles are provided. The method includes sensing overcurrent in a power factor correction circuit of the charging device and turning off the power factor correction circuit upon sensing overcurrent. An output voltage of the power factor correction circuit is then increased when the number of generations of sensed overcurrent is equal to or less than a predetermined first reference value and the power factor correction circuit is turned on.
