ABSTRACT:
The object is to provide a power converter which is capable of minimizing an extent to which the power converter components other than the semiconductor module are thermally affected by the heat originating from the semiconductor module.A casing houses: semiconductor modules20, 30constituting a main circuit for power conversion; a capacitor50electrically connected to the main circuit; drive circuits70, 71that provide the main circuit with a drive signal used in power conversion operation; a control circuit74that provides the drive circuit with a control signal used to prompt the drive circuit to provide the drive signal. Within the casing, a cooling chamber including a coolant passage28is formed, and a chamber wall of the cooling chamber is formed with a thermally conductive material. At least the semiconductor modules20, 30are housed inside the cooling chamber, and at least the capacitor50and the control circuit74are disposed outside the cooling chamber.
