Abstract: A method and apparatus for converting DC power to AC power. For example, apparatus for converting DC power to AC power comprises an input adapted to be coupled to a high-powered distributed generator having a maximum voltage at a first voltage and an arc fault mitigation device, coupled to the input, for providing a second voltage at the input that is lower than the first voltage, where a difference between the first voltage and the second voltage is not large enough to cause an arc.

Abstract: Embodiments of planar transformer winding assemblies are provided herein. For example, a transformer winding assembly comprises a primary winding configured to connect to an upper surface of a flexible substrate comprising a plurality of conjoined annular rings, the primary winding runs along the plurality of conjoined annular rings in a first configuration and a secondary winding configured to connect to a lower surface of the flexible substrate, the secondary winding runs along the plurality of conjoined annular rings in a second configuration different from the first configuration.
