  • High speed charge control for power switching devices
    Patent number: 9755434
    Abstract: Disclosed are systems, devices, apparatus, circuits, methods, and other implementations, including a system that includes one or more power switching devices that receive power delivered by a power unit, and a high-speed charge control circuit electrically coupled to the one or more power switching devices. The high-speed charge control circuit includes an optocoupler coupled to the power unit and further coupled to a first switching device of the high-speed charge control circuit, the first switching device actuated based on output of the optocoupler to establish an electrical path to discharge at least a portion of electrical charge present at least on the one or more power switching devices when power delivery from the power unit is stopped.
    Type: Grant
    Filed: September 30, 2015
    Date of Patent: September 5, 2017
    Assignee: Crydom, Inc.
