Abstract: A ground fault circuit interrupter (GFCI) includes a sense coil to determine a current flow in a power circuit coupled between a power source and a load. The GFCI also includes a switching device configured to disconnect the power source from the load. The GFCI further includes a controller that controls the switching device based on the current flow in the power circuit. The GFCI additionally includes an electrical power supply that provides electrical power to the switching device. The power supply is electrically separate and isolated from the power circuit. The GFCI may be used to monitor a power circuit connected to a tuned resonant circuit, such as a source or capture resonator of a wireless power transfer system, since inductive elements in the switching device, such as solenoids, are isolated from the power circuit and therefore cannot unbalance a tuned resonant circuit connected to the power circuit.
