    Abstract: An apparatus includes a power semiconductor switch, a driver circuit configured to drive a control terminal of the power semiconductor switch, and a control circuit configured to apply a control signal to the driver circuit responsive to a comparison of a reference voltage to a voltage at the control terminal of the semiconductor switch. In some embodiments, the power semiconductor switch may include a field effect transistor (FET), such as a wide bandgap silicon carbide (SiC) MOSFET. The control terminal may include a gate terminal of the FET, and the voltage at the control terminal may include a gate voltage.

    CPC classification number: H02P27/06

    Abstract: An apparatus includes a plurality of DC buses and a plurality of inverter circuits, respective ones of which are coupled to respective ones of the plurality of DC buses. The apparatus further includes a control circuit configured to generate a representative DC voltage signal based on DC voltage signals for respective ones of the DC buses, to generate a first modulation control signal from the representative DC voltage signal, to generate second modulation control signals for the respective inverter circuits from the representative DC voltage signal and the first modulation control signal that are normalized based on the DC voltage signals for the buses and the representative DC voltage signal, and to modulate the inverter circuits responsive to respective ones of the second modulation control signals. The representative DC voltage signal may represent a maximum of the DC voltages for the respective DC buses.

    Abstract: An apparatus includes a mechanical switch and a solid-state switch, such as a diamond switch or antiparallel-connected thyristor pair, coupled in series between an AC source and the load, such as a substation input transformer. The control circuit may be configured to connect the AC power source to the load by closing the mechanical switch and turning on the solid-state switch thereafter. The control circuit may be configured to interrupt a connection of the AC source to the load by turning off the solid-state switch and closing the mechanical switch thereafter. Operations of the switches may be coordinated with a fuse coupled in series with the solid-state switch to address different types of fault conditions.

    Abstract: A system for high-voltage interconnecting and interfacing can include: a package for a circuit, wherein the package comprises a housing for the circuit; and a gate connector located centrally on a face of an exterior surface of the housing, wherein the gate connector enables wiring outside the package to couple to the gate connector from any of a plurality of directions. In certain embodiments, the package for the housing further comprises a pressure applicator about an exterior surface of the housing; and the system further comprises a leadline that extends from the circuit within the housing and beyond the exterior surface through an aperture in the housing, wherein the leadline can be deformed over the pressure applicator at the exterior surface such that the pressure applicator can apply pressure to the leadline against a contact surface of a second structure.
