Abstract

An object of the present invention is to improve the reliability of a power converter against electromagnetic noise. A power converter according to the present invention includes: a power semiconductor circuit unit; a DCDC converter circuit unit; a first drive circuit board that outputs a drive signal to the power semiconductor circuit unit; a second drive circuit board that outputs a drive signal to the DCDC converter circuit unit; and a control circuit board that outputs a first control signal for controlling the first drive circuit board and a second control signal for controlling the second drive circuit board, in which the control circuit board is arranged at a position facing the second drive circuit board with the power semiconductor circuit unit and the DCDC converter circuit unit interposed therebetween, the first drive circuit board is arranged to be substantially parallel to an array direction of the control circuit board and the second drive circuit board, and the first drive circuit board has a relay wiring that relays the second control signal output from the control circuit board to the second drive circuit board.
