Abstract
An output voltage control method and apparatus are provided. The method includes sensing output voltages of a DC-DC converter and a high-voltage battery and sensing an inductor current flowing through an inductor in a boost circuit at a front end of the DC-DC converter. In addition, the method includes varying a gain of an output voltage controller of the DC-DC converter based on a difference of the sensed inductor current with respect to an inductor current at the center point in a specified region.
