High voltage power chip module

Abstract

A power die module using a compression connection to a power die in a small package with corona extenders positioned around short efficient path exterior electrical connections. The module is built from a baseplate with connected sidewalls forming an interior compartment holding a power substrate with attached threaded inserts. A printed circuit board bolted to the power substrate with high voltage power die compressively held between the board and the substrate. The compressive hold enhances the electrical connections between the contacts on the top and bottom of the power die and either the power substrate or the printed circuit board. Exterior blade connectors extend upward from the printed circuit board through blade apertures in a lid that covers the interior compartment. The lid includes corona extenders positioned around the blade apertures to allow for high voltage applications while maintaining a small size lightweight package. The sidewall has a perimeter that also includes one or more corona extenders.
