Abstract
In order to widen an operational input voltage range of a power conversion apparatus and obtain a maximum efficiency value comparable to that in a case where the operational input voltage range is not widened by changing software but not hardware, provided is a power conversion apparatus, in which a control section () controls a current input to an inverter circuit () to cause a DC output voltage from an AC/DC converter section () which is a voltage across a smoothing capacitor () to follow a target voltage and to cause an input power factor from an AC power supply () to approach one, to thereby maintain a DC voltage from a single-phase inverter (), and adjusts the target voltage for the DC output voltage from the AC/DC converter section () in accordance with a voltage of the AC power supply ().
