A bridgeless power factor correction circuit includes: a first leg composed of a series circuit with a first rectifier and a first switch; a second leg that is composed of a series circuit with a second rectifier and a second switch and is connected in parallel to the first leg; a smoothing capacitor connected in parallel to the first leg; a snubber circuit that is connected between a first connection point, which is located between the first rectifier and the first switch and is connected via a first inductor to one end of an AC power supply, and a second connection point, which is located between the second rectifier and the second switch and is connected via a second inductor to another end of the AC power supply; and a control circuit that executes on/off control of the first switch and the second switch.
