Abstract
In a non-contact power supply system, each of a plurality of non-contact power supply devices includes a filter circuit connected to an inverter to convert power supplied from a power source into AC power and including a reactor and capacitors. The non-contact power supply system includes an electrostatic coupler to electrostatically couple one non-contact power supply device to another non-contact power supply device. The electrostatic coupler includes two capacitors electrically connected in parallel, and a different-phase coil between the filter circuit of the one non-contact power supply device and the two capacitors. The different-phase coil includes an inductance component when a short-circuit or a ground fault occurs.
