A power factor correcting converter includes a DC-DC converter to convert a DC voltage, which is formed by rectifying an AC voltage of an AC power source through a rectifier, into a DC voltage of the DC-DC converter and a step-up converter to step up the DC voltage of the DC-DC converter. Secondary windings of a transformer Ta in the DC-DC converter are directly connected to the step-up converter.
