Abstract
A power switching device includes a buffer circuit, a filter circuit, a transformer, a restoration circuit, a conditioning circuit and a power switch. The buffer circuit provides a unipolar buffer output voltage dependent on an input voltage and a control voltage. The filter circuit blocks a direct component of the buffer output voltage which is added on the secondary side of the transformer by the restoration circuit. The power switch is controlled by a unipolar conditioning voltage provided by the restoration circuit to the conditioning circuit. The power switching device acts as a plug and play module and can be used and operated in a flexible and easy manner.
