Abstract
A switch of an inverter module is disposed in a coolant channel, is configured to be immersed in coolant in the coolant channel, and includes: a first terminal disposed on a first plane and configured to connect to a direct current (DC) reference potential; a second terminal disposed on a second plane and configured to connect to an alternating current (AC) reference potential; a gate, an emitter, and a collector; first cooling features that extend away from the first and second planes, that directly contact the first terminal, and that are configured to allow coolant flow therethrough; and second cooling features that extend away from the first cooling features, the first plane, and the second plane, that directly contact the second terminal, and that are configured to allow coolant flow therethrough.
