Power Converter
First Claim
1. A power converter, comprising:
- a semiconductor module constituting a main circuit for power conversion;
a capacitor electrically connected to the main circuit;
a drive circuit that provides the main circuit with a drive signal used in power conversion operation;
a control circuit that provides the drive circuit with a control signal used to prompt the drive circuit to provide the drive signal; and
a cooling chamber comprising a coolant passage formed therein, all housed inside a casing, wherein;
a chamber wall of the cooling chamber is formed with a thermally conductive material;
at least the semiconductor module is housed inside the cooling chamber; and
at least the capacitor and the control circuit are disposed outside the cooling chamber.

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 modules 20, 30 constituting a main circuit for power conversion; a capacitor 50 electrically connected to the main circuit; drive circuits 70, 71 that provide the main circuit with a drive signal used in power conversion operation; a control circuit 74 that 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 passage 28 is formed, and a chamber wall of the cooling chamber is formed with a thermally conductive material. At least the semiconductor modules 20, 30 are housed inside the cooling chamber, and at least the capacitor 50 and the control circuit 74 are disposed outside the cooling chamber.
