PURPOSE: A bidirectional converter control method is provided to control operation frequency of a transformer and to enhance optimal state. CONSTITUTION: A bidirectional converter control method comprises: a step of converting the mode of the converter from a buck mode to boost mode; a step of determining change of output capacity of the converter; and a step of enhancing operation frequency of a switch device according to operation mode of the converter in case of increasing output capacity.
