Abstract: A universal AC to DC converter may be configured to convert alternating current (AC) to direct current (DC), such as for use in aerospace applications. The disclosure relates to a single universal power electronic converter capable of converting an AC input voltage, such as a line to neutral input voltage of either 115 Vrms or 230 Vrms nominal to 28 V DC.

Abstract: A power distribution cabinet includes a housing having walls that define an interior space for housing electric components. A capacitive sensor is located on an interior surface of one or more of the walls. The capacitive sensor includes a first conductive layer located proximate to the interior surface of the wall, a second conductive layer located distal from the interior surface of the wall, and a dielectric layer located between the first and second conductive layers. First and second output terminals are connected to the first and second conductive layers of the capacitive sensor to provide an output representative of displacement current within the power distribution cabinet.
