Abstract

The present invention relates to a power transmitting device, a power receiving device, and a vehicle equipped with the power receiving device. Regarding the filter circuit (200), when the frequency of the inverter (100) is set to ω, the ratio of the output voltage of the filter circuit (200) to the input voltage is set to a1, and an arbitrary design value is set to Z01 In the case of , the inductance of the coil (212) is set to Z01 / ω, the capacitance of the capacitor (214) is set to (a1+1) / (a1·ω·Z01), and the inductance of the coil (216) is set to a1 • Z01 / ω, the capacitance of the capacitor (218) is set to (a1+1) / (a12·ω·Z01).

Description

technical field [0001] The present invention relates to a power transmitting device, a power receiving device, and a vehicle equipped with the power receiving device, and more particularly to a power transmitting device, a power receiving device used in a power transmission system that transmits electric power from a power transmitting device to a power receiving device in a non-contact manner. device and a vehicle equipped with the power receiving device. Background technique [0002] As a power transmission method, non-contact power transmission that does not use a power supply line or a power transmission cable is attracting attention. For example, Japanese Patent Application Laid-Open No. 2014-54095 discloses such a contactless power supply system. In this contactless power supply system, a filter circuit (matching unit) is provided between the power supply unit and the power transmission unit in order to suppress harmonic noise generated from an AC power supply (power ...
