  • DC output solid state contactor assembly
    Patent number: 12021510
    Abstract: In one embodiment, there is provided a DC output solid contactor assembly having a housing enclosure and a cavity within the enclosure; one or more SOT-227 isolated semiconductor modules and its variants in a stand-alone, parallel or series configuration; a novel drive circuit board mounted on at least one of the modules with input power terminals for coupling to an input control source; and gate impulse output terminals coupling to one or more semiconductor's gate electrodes. The drive circuit includes a voltage priming system that converts input control signal to an isolated and optimal gate driving voltage level; and positive and negative output power terminals for coupling to the electrical load side.
