    摘要: 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.

    摘要: 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.
