Abstract

The AC-DC converter (2) includes a rectifier circuit (20) having a switching element (215) and rectifying a power supply voltage applied from an AC power supply (1), a capacitor (216) connected to DC buses (9a, 9b) and smoothing an output voltage of the rectifier circuit (20), a reactor (212) arranged on the AC power supply (1) side of the capacitor (216), and a control unit (6) generating a switching signal for controlling the switching element (215). The control unit (6) generates the switching signal so that harmonic components included in a power supply current flowing between the AC power supply (1) and the rectifier circuit (20) comply with a harmonic standard value for the power supply current.
