Abstract
A method for changing a capacitance value of an output capacitor of a power factor corrector (PFC) includes applying AC power to a power conversion circuit. It is sensed whether an instantaneous power failure occurs in the AC power. Output capacitors of the PFC of the power conversion circuit are connected in parallel to each other to increase capacitance values of the output capacitors, when it is sensed that the instantaneous power failure does not occur in the AC power.
