Abstract: A method for assembly of a transfer switch is disclosed that includes a power switch device with a number engagement landings and a printed circuit board defining an opening bordered by a number of tabs. The tabs engage the landings as the switch device extends through the openings, and can be fastened together.

Abstract: One system of the present application includes an electronic assembly with a heat dissipating device, printed wiring board with electronic circuitry, bus bar, insulative grommet, and fastener. The board defines a bus with an interconnection pad and a board opening. The bus bar connects with the interconnection pad and defines a bar opening with a beveled shoulder portion that align with the board opening to define a passage to a fastening site of the heat dissipating device. The grommet defines a distal end portion opposite a proximal end portion shaped with a flange. The distal end portion is inserted into the passage with the flange abutting the beveled shoulder portion. The fastener extends through the grommet to provide a mechanical connection of the board and bar to the site and maintain thermal coupling between the board and device while the grommet electrically insulates the fastener from the bar.

Abstract: An electric power system includes a variable speed generator driven by an engine and an electrical energy storage device. The generator and the storage device are coupled to a variable voltage DC bus. An inverter converts DC electricity from the DC bus to AC electricity for one or more electrical loads. A detector is included to monitor electric current provided to the DC bus by the storage device and provide a corresponding signal. Control circuitry is responsive to this signal to regulate power output from the storage device to the DC bus.
