Power semiconductor module
First Claim
1. A power semiconductor module comprising:
- a baseplate supporting one or more electronic devices on a surface thereof;
at least one terminal block having one or more power terminals retained thereon and having outwardly extending terminal elements;
a compliant mounting for compliantly supporting the terminal block on the same surface of the baseplate as the electronic devices; and
a cover hermetically sealed to the baseplate and having an opening for each of the terminal elements, each of the terminal elements extending through the cover and being hermetically sealed thereto.

Abstract
An electronic module or package is disclosed for providing high reliability and high performance operation. The package comprises a hermetically sealed enclosure having a metallic baseplate and a ceramic cover, and containing one or more circuits or devices therein which typically are power rectifiers, bridges or power control circuitry. One or more power terminals are disposed on a terminal block compliantly supported on or above the baseplate, the terminals extending through the cover in hermetically sealed manner. Signal or control terminals may also be disposed on a terminal block compliantly supported on or above the baseplate, these terminals also extending through the cover in hermetically sealed manner. An adapter plate may be mounted on the cover and containing a plurality of terminals connected to the module terminals. The terminals of the adapter plate can be in any configuration to suit user requirements without requiring a change in the terminal configuration of the module itself. The adapter plate may also contain active and/or passive circuitry.
