1. A power convertor comprising:
- a power module including a power semiconductor for converting DC current to AC current;
a rotating electric machine control circuit board outputting timing signals for switching the power semiconductor;
a connector transmitting input signals to the rotating electric machine control circuit; and
a noise reduction board including a bypass capacitor for removing noise superimposed on each of the input signals;
wherein the noise reduction board is configured to be physically separated from the rotating electric machine control circuit board such that the noise reduction board is on a board different from the rotating electric machine control circuit board.
