An apparatus to convert a direct current to an alternating current includes a power module (3) disposed between an input terminal (1a) of the direct current and output terminal of the alternating current, the power module comprising an on/off switch element, a first smoothing condenser (41) connected in parallel with the power module (3), a second smoothing condenser (42) connected in parallel with the power module (3), the second smoothing condenser (42) comprising an electrostatic capacity less than the first smoothing condenser (41), a first wiring (41a) connecting the power module (3) and the first smoothing condenser (41), and a second wiring (42a) connecting the power module (3) and the second smoothing condenser (42), the second wiring (42a) comprising an inductance greater than the first wiring (41a). |
