Claim Text:
1. A power converter comprising: a boost circuit configured to boost a voltage of a direct-current (DC) power supply; a single-phase inverter configured to output an alternating-current (AC) voltage based on a voltage output from the boost circuit; a current controller configured to generate a voltage reference based on a difference between a current output from the single-phase inverter and a current reference; and a power conversion controller configured to control the single-phase inverter to generate a first portion of the AC voltage, and to control the boost circuit to generate a second portion of the AC voltage, the first portion according to the voltage reference of which an absolute value is smaller than the voltage of the DC power supply, and the second portion according to the voltage reference of which an absolute value is greater than the voltage of the DC power supply.
