Latest Patents

- Semiconductor Switching Module Optimized for Resistance to Short Circuits. This invention describes a semiconductor switching module with a housing designed to release pressure generated during a short circuit. Openings in the housing may be sealed by thin walls that prevent access to current-carrying parts during normal operation, while allowing pressure to destroy or remove the walls during a short circuit.

- Power Semiconductor Module. This invention describes a plate-type substrate carrying at least one component and a base plate that dissipates heat through the substrate. A supporting apparatus maintains thermal contact between the substrate and base plate using a central pressure bolt and multiple stamps extending in different directions. In the mechanically unloaded state, the stamps are positioned at non-uniform distances from the substrate.
