Mechanical layout for half-bridge power module that is optimized for low inductance

摘要

Disclosed is a mechanical layout for a half-bride power module that is optimized for low inductance. In one embodiment, a first power module and a second power module are mounted on each side of a heat sink. An inductance cancelling bus bar is wrapped around the heat sink, the first power module and the second power module in a loop.

主权项

1. A half-bridge power module, comprising:
a heat sink; a first power module mounted on one side of the heat sink; a second power module mounted on another side of the heat sink opposite the side that the first power module mounts thereto; and an inductance cancelling bus bar wrapped around the heat sink, the first power module and the second power module in a loop.
