Publication number: 20240097496Abstract: A power supply system includes: a power transmission circuit provided on the ground side; a high frequency generation circuit that supplies high-frequency electric power to the power transmission circuit; a measurement unit that measures a physical quantity corresponding to the degree of coupling between the power transmission circuit and a power reception circuit provided in a vehicle; and a control unit. When the degree of coupling is determined, based on the measured physical quantity, to be lower than a predetermined degree, the control unit sets the impedance of the power transmission circuit to a first impedance and thereby sets the power transmission circuit to a non-resonant state. In contrast, when the degree of coupling is determined to be not lower than the predetermined degree, the control unit sets the impedance of the power transmission circuit to a second impedance and thereby sets the power transmission circuit to a resonant state.Type: ApplicationFiled: November 29, 2023Publication date: March 21, 2024Applicant: DENSO CORPORATIONInventors: Yusei NAKAYASHIKI, Masaya TAKAHASHI, Nobuhisa YAMAGUCHI, Eisuke TAKAHASHI
