Abstract: A gate network of a silicon-carbide (SiC) power conversion device includes a plurality of gate electrodes of SiC metal-oxide-semiconductor-based (MOS-based) transistor device cells disposed in an active area of the SiC power conversion device, and a gate pad disposed in a gate pad and bus area of the SiC power conversion device. The gate network also includes a gate bus disposed in the gate pad and bus area of the SiC power conversion device, wherein the gate bus extends between and electrically connects the gate pad to at least a portion of the plurality of gate electrodes in the active area of the SiC power conversion device. At least a portion of the gate pad, the gate bus, the plurality of gate electrodes, or a combination thereof, of the gate network have a positive temperature coefficient of resistance greater than approximately 2000 parts-per-million per degree Celsius (ppm/° C.).

Abstract: The application discloses the control of switches, such as metal-oxide semiconductor field effect transistors (MOSFETs) devices, during surge events. The switch controllers and methods for operation thereof discuss methods for providing driving signals to the switch for adjusting the mode of operation based on the voltage and/or current thresholds as sensed by the system and/or by the switch controller.

Abstract: A power electronic device includes at least one inductor configured to couple to a first capacitor and a second capacitor. The power electronic device includes a controller configured to control a first current conducting through the inductor and a second current conducting through the inductor. The first and second currents conduct in opposite directions with respect to each other, and the first and second currents interact with each other through the inductor such that a net direct current (DC) component through the inductor is approximately zero.

Abstract: The systems and methods described herein relate to an adapter driver board for parallel operation of power modules. The systems and methods receive an electrical signal at an input interface of a high voltage adapter board. The systems and methods further deliver the electrical signals to first and second switches along corresponding first and second conductive traces. The first conductive trace extends along the high voltage adapter board and is conductively coupled to the input interface and the first switch. The second conductive trace extending along the high voltage adapter board and is conductively coupled to the input interface and the second switch. The first and second conductive traces are each configured to have an inductance substantially the same. The systems and methods synchronously activate the first and second switches based on the electrical signal.
