  • Patent number: 11784555
    Abstract: A method and apparatus for converting DC power to AC power. For example, apparatus for converting DC power to AC power comprises an input adapted to be coupled to a high-powered distributed generator having a maximum voltage at a first voltage and an arc fault mitigation device, coupled to the input, for providing a second voltage at the input that is lower than the first voltage, where a difference between the first voltage and the second voltage is not large enough to cause an arc.
    Type: Grant

  • Publication number: 20170133844
    Abstract: A method and apparatus for using distributed energy resources (DERs) to detect a fire event. In one embodiment, the method comprises receiving, at a controller comprising at least one processor, temperature data from at least one power conditioner of a DER; analyzing, by the controller, the temperature data with respect to at least one temperature reference; determining, by the controller and based on analyzing the temperature data with respect to the at least one temperature reference, whether a fire event exists; and when it is determined that a fire event exists, performing, by the controller, at least one action for addressing the fire event.

  • Patent number: 9531191
    Abstract: A method and apparatus for power imbalance correction comprising: a plurality of converters for converting a plurality of DC inputs to a multi-phase AC output, and coupling the multi-phase AC output to a multi-phase AC line, and a controller coupled to the plurality of converters. The controller determining whether phases of the multi-phase AC output are balanced, and controlling when all phases of the multi-phase AC output are not balanced, at least one converter of the plurality of converters to balance the multi-phase AC output.

  • Patent number: 4947256
    Abstract: An adaptive architecture for video effects allows a transformed image from a digital video effects (DVE) system to be inserted at any desired point along a video path through a production switcher while maintaining strict timing reqirements between the digital video effects system and the production switcher. The transformed image from the DVE system is input to a primary input bus as well as to a fill video input of a dowstream keyer (DSK) for the production switcher. A key signal from the DVE system is input to an effects key input and a key input of the DSK for the production switcher. The DVE system has a genlock timing system that provides a variable output timing signal to synchronize the transformed image with the video of the production system at the desired point of insertion along the video path.
