Latest Patents

One of her latest patents is the "Sealed Interface Power Module Housing." This invention describes various sealed interfaces for power modules. In one example, the sealed interface includes a printed circuit board with a contact pad for power conduction to a bus bar. It also features a semiconductor module with at least one power transistor, a terminal pin electrically coupled to the power module, and a housing that includes an open terminal aperture. The design ensures that the printed circuit board is seated upon the open terminal aperture, effectively sealing it while allowing the terminal pin to contact the contact pad within the aperture. This innovative design includes a transitional feature to reduce electric field intensity around the interface.

Another notable patent is the "Semiconductor Module Arrangement." This invention focuses on a switching module structure that incorporates a low-impedance path to ground. It utilizes a parasitic capacitance of an insulating substrate and a further insulating substrate placed in series with the low impedance current path. The arrangement connects a conductive layer to input voltage rails using a single decoupling capacitor, or preferably, a midpoint of the voltage rails formed by a series connection of decoupling capacitors. This design effectively maintains a large portion of common mode currents due to high dV/dt slew rates of SiC and GaN transistors within the switching module.
