Abstract:
1. A power converter, comprising: a voltage source rectifier converting AC power obtained from an AC power source into a DC power output; a DC power source; a DC voltage conversion circuit converting a DC voltage obtained from the DC power source into a different DC voltage and outputting a corresponding DC power; and a load driving circuit converting at least either the DC power output of the voltage source rectifier or the DC power output of the DC voltage conversion circuit into AC power to drive an AC load, wherein the DC power source is connected to the DC voltage conversion circuit to convert a voltage of the DC power source and supply a resultant voltage to the load driving circuit, and wherein the DC power source is connected to the voltage source rectifier via a DC power supply circuit and inductance elements, and the voltage source rectifier is controlled as a DC chopper, to convert the voltage of the DC power source and supply a resultant voltage to the load driving circuit.
