Abstract
A method for controlling a power source semiconductor may include: supplying, by a switching frequency supply unit, preset respective reference switching frequencies to a plurality of elements which are operated according to a respective switching frequency; sensing, by a control unit, sensing interference in the plurality of elements, based on operations of the elements according to the respective reference switching frequencies; setting, by the control unit, bandwidths for the respective reference switching frequencies when the interference in the plurality of elements is sensed; and increasing, by a bandwidth adjusting unit, bandwidth of the respective reference switching frequencies supplied through the switching frequency supply unit, based on the bandwidths for the respective reference switching frequencies.
