Title:
CONTACTLESS POWER FEEDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/181280
Kind Code:
A1
Abstract:
A contactless power feeding system for contactlessly feeding electric power from a power transmission device to a power reception device, wherein, at the operating frequency of an angular frequency ω0: the capacitance of a primary side capacitor (114) of a primary side resonance circuit (110) is set to resonate with a self-inductance L1 of a primary side coil (112); the capacitance of a tertiary side capacitor (314) of a tertiary side resonance circuit (310) is set to resonate with a self-inductance L3 of a tertiary side coil (312); and the capacitance of a secondary side capacitor (214) of a secondary side resonance circuit (210) is set such that the reactive power component of alternating-current power due to the respective self-inductances and mutual inductances of the primary side coil (112), the secondary side coil (212), and the tertiary side coil (312) decreases.
