摘要： A power supply apparatus is provided with a first bridge rectifier circuit (5) connected to a three-phase alternating current power supply (1) via first reactors (2, 3, 4), and a smoothing capacitor (13) that smoothes a direct current output of the first bridge rectifier circuit (5). A second bridge rectifier circuit (6) is connected to alternating current input terminals of the first bridge rectifier circuit (5) via second reactors (7, 8, 9), capacitors (10, 11, and 12) are provided respectively between each two terminals of alternating current input terminals of the second bridge rectifier circuit (6), and direct current output terminals of the second bridge rectifier circuit (6) are respectively connected in parallel to direct current output terminals of the first bridge rectifier circuit (5). Thus, it is possible to reduce a harmonic current and improve an input power factor with a simple configuration.
