Title: POWER CONVERSION DEVICE
Abstract:
The purpose of the present invention is to improve the reliability of a power conversion device with respect to electromagnetic noise. A power conversion device according to the present invention comprises: a power semiconductor circuit unit; a DC-DC converter circuit unit; a first drive circuit board for outputting a drive signal to the power semiconductor circuit unit; a second drive circuit board for outputting a drive signal to the DC-DC converter circuit unit; and a control circuit board which outputs a first control signal for controlling the first drive circuit board and a second control signal for controlling the second drive circuit board. The control circuit board is disposed at a position facing the second drive circuit board and interposed between the power semiconductor circuit unit and the DC-DC converter circuit unit; the first drive circuit board is disposed so as to be approximately parallel to the arrangement directions of the control circuit board and the second drive circuit board; and the first drive circuit board has a relay wire for relaying the second control signal, which is output from the control circuit board, to the second drive circuit board.
