Abstract
Provided is a power converter capable of being miniaturized while securing noise resistance and insulation between a power semiconductor module and a drive circuit board. The power converter according to the present invention includes a power semiconductor module that converts DC power into AC power, a driving signal circuit board that outputs a driving signal for driving the power semiconductor module, and a resin support member that supports the driving signal circuit board, in which the power semiconductor module has a signal terminal that transmits the driving signal and a main terminal that transmits an input of the DC power and an output of the AC power, the support member is disposed between the driving signal circuit board and the power semiconductor module, the signal terminal and the main terminal are provided on a side of the power semiconductor module that faces the support member, and a metal shielding plate is embedded in a region between the driving signal circuit board in the support member and the main terminal.
