Problem to be Solved A switching element of a power converter generates a low voltage, using a current flowing in the power converter, and supplies a power to drive itself. Solution A switching element 108 of a power converter for conversion from direct current into alternate current or from alternate current into direct current includes: a terminal 208 and a terminal 209 which are used in building the switching element 108 itself in the power converter; a capacitor 203, a high-side controllable switch 201H and a low-side controllable switch 201L enabling outputting the voltage of the capacitor 203, the voltage being output between the terminal 208 and the terminal 209, and a self-supply power source 206 for supplying a power to drive the bi-directional chopper switching element 108 itself, using a current flowing in the capacitor 203.

A power conversion apparatus (102) includes arms (104) in each of which one or more unit converters (105) each including a capacitor (203) and capable of outputting an arbitrary voltage are connected in series, and a point P as a first node to which one ends of the respective arms (104) are Y-connected, and a point N as a second node to which a neutral terminal of the rotary electric machine (103) is connected. The other ends of the respective arms are connected to one ends of respective phase windings of a rotary electric machine.

A control apparatus for use with a voltage source converter (102) includes legs (104) each of which is configured by a plurality of converter modules (108) each having capacitors (203). Each of the legs has a first terminal on a positive side and a second terminal on a negative side. The control apparatus is operative to create command pulses for operating the converter modules to operate the converter modules. The command pulses have a frequency that is a non-integral multiple of a frequency of a system voltage (VGR, VGS, VGT). The non-integral multiple is 3.5, for example.
