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 1):
A power conversion device comprising:\n three inverters each of which is configured to convert DC power of a DC bus into single-phase AC power, and a controller configured to control the three inverters so as to generate three-phase AC power, wherein the controller is further configured to, for each of the three inverters:\n generate a fundamental wave for generating one-phase AC power constituting the three-phase AC power, the fundamental wave having a fundamental frequency; \n generate an adjustment wave having a frequency that is triple the fundamental frequency of the fundamental wave; \n add the adjustment wave to the fundamental wave to generate a phase voltage, wherein an initial phase of the adjustment wave prior to generating the phase voltage is offset from an initial phase of the fundamental wave so as to reduce a voltage ripple occurring in the DC bus at a frequency that is double the fundamental frequency of the fundamental wave; and \n output the phase voltage to generate the three-phase AC power.
