Abstract:
A power conversion device includes three inverters configured to convert DC power of DC buses into single-phase AC power, and a controller configured to control the three inverters so as to generate three-phase AC power. The controller is configured to generate a fundamental wave command for generating one-phase AC power constituting the three-phase AC power, and to generate an adjustment wave command having triple the frequency of the fundamental wave command. Additionally, the controller is configured to output a phase voltage command, in which the adjustment wave command is superimposed on the fundamental wave command, and to determine an initial phase of the adjustment wave command to be offset from an initial phase of the fundamental wave command so as to reduce a voltage ripple occurring in the DC buses at double the frequency of the fundamental wave command.

Claim (Index 16):
A power conversion method comprising:\n generating a fundamental wave for generating one-phase AC power of three-phase AC power for each of three inverters configured to convert DC power of a DC bus into single-phase AC power, the fundamental wave having a fundamental frequency; generating, for each of the three inverters, an adjustment wave having a frequency that is triple the fundamental frequency of the fundamental wave; adding, for each of the three inverters, the adjustment wave to the fundamental wave to generate a phase voltage, wherein an initial phase of the adjustment wave is offset from an initial phase of the fundamental wave so as to reduce a voltage ripple occurring in the DC bus at double the fundamental frequency of the fundamental wave; and outputting, for each of the three inverters, the phase voltage to generate the three-phase AC power.
