    Abstract: A static transfer switch is provided for supplying power to a load alternately from two different power sources. Switching between the two power sources may occur within a fraction of one electrical cycle. In response to sensing degraded performance in the power source supplying the load, a main circuit is turned off with a resonant turn off circuit. The resonant turn off circuit is shared between the main circuits of two different power sources such that the resonant turn off circuit is connected to the main circuit of whichever power source is currently supply power to the load.

    Abstract: An automatic charging device and method is described that is positionable to access an underside of an electrical vehicle that facilitates hands-free connection of a vehicle-side electrical connector with a floor unit electrical connector. The automatic charging device includes a floor unit, a first slidable carriage disposed in the floor unit, a second slidable carriage disposed in the floor unit, a pivotal link coupled to the floor unit electrical connector, and a lift mechanism connected to the second slidable carriage and the pivotal link. The floor unit electrical connector is arranged to rise away from the floor unit in a direction of the vehicle-side electrical connector to facilitate a mating of the vehicle-side electrical connector and the floor unit electrical connector. The first and the second slidable carriages are configured to move in a linear xy-direction, respectively, and the lift mechanism is configured to move in a linear z-direction.

    Abstract: A charge head is connected to a charge inlet of an electric vehicle to supply an electric charge to recharge the battery of the vehicle. The charge head is attached to a connecting device that moves the charge head to the charge inlet. Multiple light detectors are provided on the charge head to sense light emitted from the vehicle. The system then uses a difference in the amount of light received by different light detectors to determine a direction to move the charge head toward the charge inlet.
