Forms of the present disclosure include an input end, and an output end connected to the input end to improve a power factor through the input end. The output end includes non-electrolytic capacitors formed at both sides of an electrolytic capacitor for output, and first inductors formed between the respective non-electrolytic capacitors and the electrolytic capacitor. Therefore, forms of the present disclosure may reduce a ripple current (current stress) at a PFC output end through a CL circuit formed at a left side with respect to the electrolytic capacitor, and reduce an input ripple current (input current stress) of a DC-DC converter through an LC circuit formed at a right side.
