Abstract: Motor drive power conversion systems are provided including a rectifier and a switching inverter, wherein the switching devices of the rectifier, the inverter and/or of a DC/DC converter are silicon carbide switches, such as silicon carbide MOSFETs. Driver circuits are provided for providing bipolar gate drive signals to the silicon carbide MOSFETs, including providing negative gate-source voltage for controlling the off state of enhancement mode low side drivers and positive gate-source voltage for controlling the off state of enhancement mode high side drivers.

Abstract: A human interface module includes a body. At least one input device and at least one output device are connected to the body. A mounting protrusion projects outwardly from the body and that is adapted to be received through a mounting aperture defined in a door or other cabinet panel for fixedly securing said body to the panel. The mounting aperture can be punched and include an alignment notch that receives a locator nib of the mounting protrusion. A nut can be advanced on a threaded portion of the mounting protrusion to secure the body to the panel. The body can be a bezel that receives a removable interface module. A USB Type-C or other electrical connector can be connected to the body and is adapted to mate with a corresponding mating connector of a cable. The connector can be accessible through a hollow core of the mounting protrusion.
