Abstract
Heat generation of a converter is suppressed. An inverter applies an AC voltage converted from a DC voltage to supply power to an AC load. The power can be reduced when a voltage value Vac of the AC voltage converted into the DC voltage by the converter is less than a first value Vt1 (steps S84, S85). Figure 2
