Abstract: Embodiments of this present disclosure may include a system with a first power converter and a control system. The first power converter may supply a first output power to a first backplane at least sometimes concurrent to a second power converter supplying a second output power to a second backplane. The control system may be electrically coupled to the first backplane and the second backplane. The control system may balance a first electrical property and a second electrical property provided to each of one or more load components electrically coupled to the first backplane and the second backplane.

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.
