Abstract:
1. A power conversion system comprising: a first voltage source; a second voltage source; a multiple-phase alternating current motor; a switch section configured to produce an output pulse based on first and second output voltages of the first and second voltage sources, respectively, to drive the multiple-phase alternating current motor; and a control unit configured to control the switch section including the output voltage command value computing section of the control unit being further configured to compute the first and second output voltage command values based on a first output voltage command vector and a second output voltage command vector when the first voltage source is to be charged and the second voltage source is to be discharged, the first output voltage command vector corresponding to the first output voltage command value of the first voltage source satisfying the target charged power, the second output voltage command vector corresponding to the second output voltage command value of the second voltage source, the first and second output voltage command vectors being determined so that
