Document Type and Number:
WIPO Patent Application WO/2023/153000
Kind Code:
A1
Abstract:
In a non-contact power supply system 110, each of a plurality of non-contact power supply devices 1A, 1B, 1C, 1D, 1E has a filter circuit 9 including a reactor and a capacitor and connected to an inverter 8 which converts power supplied from a power source 2 into AC power. The non-contact power supply system 110 is provided with: an electrostatic coupling unit 112 which electrostatically couples one non-contact power supply device and another non-contact power supply device and has two capacitors C10, C20 electrically connected in parallel; and different-phase coils 114 which are respectively provided between the filter circuit 9 of one non-contact power supply device and the two capacitors C10, C20 and which have inductance components for when a short circuit or a ground fault occurs.
