Abstract:
1. A regenerative inverter device, comprising: a converter unit configured to receive single phase AC power to output DC power; a capacitor unit configured to absorb DC power being output from the converter unit; an inverter unit configured to synthesize the absorbed DC power to output the drive power of a load; and a converter controller configured to control the converter unit based on the single phase AC power and the output DC power of the converter unit, wherein the converter controller comprises: a converter gate signal generator configured to control a plurality of gates contained in the converter unit; and an input line harmonic voltage generator configured to output converter additional power having a predetermined multiple of the frequency of the fundamental frequency component of the single phase AC power with the same size as that of the fundamental frequency component of the single phase AC power to an adder connected to the input side of the converter gate signal generator.
