Kind Code:
A1
Abstract:
A power reception device (30) of a non-contact power supply system (10) in which power is supplied in a non-contact manner between a power transmission device (20) provided to a road side and the power reception device, which is provided to a vehicle side, comprises: multiple phases of power reception-side coils (31Lu, 31Lv, 31Lw), the phases being three or more phases; an iron core (35) that causes flux coupling between the power reception-side coils of the phases; and power reception-side capacitors (31Cu, 31Cv, 31Cw) respectively connected to the power reception-side coil of each phase. The power reception-side coils of the phases are arranged so that, among the inter-coil distances (Y1, Y2, Y3) between the power reception-side coils, at least one inter-coil distance differs from the other inter-coil distances, and the capacities of the power reception-side capacitors are set in accordance with the inter-coil distances.
