Abstract

The power conversion device includes: a control unit that switches between the on state in which a power module is made conductive between a drain terminal and a source terminal of the power module and the off state in which the power module is made non-conductive; a resistance element connected between the control unit and a gate terminal of the power module; and a bypass circuit in which a drain terminal of a semiconductor switching element provided for each power module is connected to the gate terminal of the power module, and a source terminal of the semiconductor switching element is connected to the source terminal of the power module, in which the control unit switches the semiconductor switching element of the bypass circuit to the on state when the power module is switched to the off state, thereby reducing occurrence of an erroneous turn-on of the power module.
