Abstract: A surge arrester system includes a surge arrester, and an active cooling system having a cooling interface in contact with the surge arrester and operative to transfer heat from the surge arrester. The active cooling system includes a forced convection apparatus operative to provide forced convection cooling. A circuit breaker system includes a power semiconductor switch and an active cooling system constructed to cool the power semiconductor switch. The active cooling system includes a forced convection apparatus configured to provide forced convection cooling. The power semiconductor switch is in contact with the active cooling system. A surge arrester is disposed adjacent to and in contact with the active cooling system. The active cooling system includes a cooling interface constructed for contact with the surge arrester and operative to provide cooling to the surge arrester. The power semiconductor switch and the surge arrester dissipate power alternatively.

Abstract: A sliding contact assembly for a DC electrical outlet receives plug contacts of an electrical plug. The assembly includes sliding contact structure having a base and a plurality of electrical sliding contacts fixed to the base. A housing includes a first end wall having an internal top surface and second end wall opposing the first end wall. The second end wall has an internal bottom surface. The housing has a side wall structure defining an internal chamber between the top surface and the bottom surface. The sliding contact structure is disposed in the housing to be movable linearly within the chamber. A spring is disposed between the top surface of the housing and a surface of the base so that when the plug contacts are completely disconnected from the associated sliding contacts, the spring rapidly forces the sliding contacts away from the plug contacts, reducing arcing energy there-between.

Abstract: A static transfer switch is provided for supplying power to a load alternately from two different power sources. Preferably, switching between the two power sources occurs within one electrical cycle. In order to control inrush currents and reduce disruption during power transfers between the two power sources, switches are provided to configure which input phases are connected to the output phases.

Abstract: An industrial electrical machine includes a stator; a rotor in magnetic communication with the stator; a plurality of windings disposed in the rotor and/or the stator; and an embedded solid state controller. The solid state controller is operative to control the operation of the industrial electrical machine. The solid state controller includes a power semiconductor switching device coupled to the plurality of windings, and includes a communication interface. The power semiconductor switching device is operative to provide switching during operation of the industrial electrical machine, and is operative to turn the electrical machine on and to turn the electrical machine off in response to a control input received by the communication interface.

Abstract: A resonant turn-off circuit is provided to disconnect an inadequate power source and transfer a load to an alternate power source. In the circuit, a main switch is turned off before the AC cycle of the power source crosses zero. As a result, the main switch may be turned off quickly to transfer electric power supplied to a load to a second power source. The circuit may include resonant switches, a capacitor, a pre-charging power supply and an inductor. When it is desired to turn off the main switch, a resonant switch is turned off to cause a voltage reversal across the switch.

Abstract: The subject matter described herein includes a fan assembly for cooling an electric machine and an electric machine incorporating such a fan assembly. One exemplary fan assembly according to the subject matter described herein includes a first fan annulus for surrounding a portion of an electric machine. The fan assembly further includes a fan drive circuit for driving the first fan annulus separately from a drive mechanism of the electric machine. The first fan annulus is configured to be, when rotating to cool the electric machine, mechanically disconnected from a housing and a rotor of the electric machine and separated from the housing by radial gap.
