Abstract:
A ground fault detection circuit includes an AC power supply and a plurality of resonance circuits. The plurality of resonance circuits are connected between at least one current path formed of a plurality of loads and the AC power supply. Each of the plurality of resonance circuits has the same resonance frequency as the frequency of the AC power supply.
