1. The power conversion apparatus for converting polyphase ac power directly to a single phase ac power, the power conversion apparatus comprising:

  • a conversion circuit including input terminals of a plurality of first switching devices connected, respectively, with phases of the polyphase ac power, and configured to enable electrical switching operation in both directions, and input terminals of a plurality of second switching devices connected, respectively, with the phases of the polyphase ac power, and configured to enable electrical switching operation in both directions; and

    a first output line for the single phase ac power connected with output terminals of the first switching devices, and a second output line for the single phase ac power connected with output terminals of the second switching devices,as a spatial arrangement,respective ones of the output terminals, of the first and second switching devices connected with a corresponding phase of the polyphase ac power, being arranged side by side in a pair geometrically between the input terminals of the first and second switching devices connected with the corresponding phase of the polyphase ac power,the output terminals, of the first switching devices connected to the corresponding phase of the polyphase ac power, being geometrically linearly arranged and connected with the first output line, and the output terminals, of the second switching devices connected to the corresponding phase of the polyphase ac power, being geometrically linearly arranged and connected with the second output line,the first output line and the second output line being drawn out geometrically between (1) the input terminals of the first switching devices and (2) the input terminals of the second switching devices.
