  • Patent number: 11899445
    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.
    Type: Grant

  • Patent number: 11860599
    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 current to a first backplane while a second power converter is concurrently supplying a second current to a second backplane. The first backplane and the second backplane may electrically couple to one or more load components and the control system. The control system may cause the first power converter to adjust the first current such that the first current and the second current are imbalanced with respect to each other in response to receiving a request to verify that the second power converter is capable of supplying the one or more load components with a target current value while the first current and the second current are imbalanced.

  • Patent number: 10389263
    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.

  • Patent number: 8710780
    Abstract: A technique is provided for verifying the proper selection, installation, communication and operability of components in power electronic systems, such as motor drives. A processing circuit is coupled to multiple components or subsystems that identify themselves to the processing system. An identification code is stored that is compared to a similar code built based upon the information reported by the components at the time of commissioning, operation or servicing. If the comparison indicates that all components are properly installed, and communicating and operative, operation may continue. The technique may be applied in parallel motor drives at a power layer level to allow separate and parallel verification of component and component operation in the parallel drives.
