Abstract

A power inverter is provided that can apply to an AC rotary machine three-phase voltages of high amplitudes and low distortion while suppressing ohmic loss attributed to current detection resisters. The power inverter includes a superimposed voltage command computing device which is configured to compute and output a superimposed voltage command depending on the difference between a maximum value and a minimum value of three-phase voltage commands; a voltage command modification device which is configured to add the superimposed voltage command to each of the three-phase voltage commands and outputting modified three-phase voltage commands; and a power output device which is configure to output the three-phase voltages based on the modified three-phase voltage commands.
