Method and apparatus for adaptive AC/DC surge protection

Abstract:

Methods and apparatus for adaptive surge protection are disclosed. An example method comprises providing load voltage to the electric load by regulating a source voltage with a surge protection device; monitoring, via a voltage detection circuit, the source voltage from an electric source, and determining, via a wiring diagnostic circuit, whether a wiring fault is detected; monitoring, via a lightning detection circuit, for the presence of lightning within a threshold distance of the surge protection device; and breaking, with a switching device, a circuit connection to stop providing the load voltage to the electric load in response to detecting at least one of: a presence of the wiring fault, the presence of lightning within the threshold distance, an overvoltage at the source voltage; or an undervoltage at the electric source.
