A power transmitting part (240) transmits the transmission power of an alternating current to a power receiver (310) in a non-contact manner. An inverter (220) is configured to adjust a power transmission frequency at a first frequency interval. A filter circuit (230) includes a capacitor, and is configured to adjust the resonance frequency of the power transmitting part (240) at a second frequency interval that is larger than the first frequency interval. A power supply ECU (250) controls the inverter (220) and the capacitor so that the frequency of adjustment of the power transmission frequency by the inverter (220) becomes higher than the frequency of adjustment of the resonance frequency by the capacitor. It is possible to adjust frequency adjustment quickly.
송전부(240)는, 교류의 송전 전력을 수전부(310)로 비접촉으로 송전한다. 인버터(220)는, 제1 주파수 간격으로 송전 주파수를 조정 가능하게 구성된다. 필터 회로(230)는, 커패시터를 포함하고, 제1 주파수 간격보다 큰 제2 주파수 간격으로 송전부(240)의 공진 주파수를 조정 가능하게 구성된다. 전원 ECU(250)는, 인버터(220)에 의한 송전 주파수의 조정 빈도가 커패시터에 의한 공진 주파수의 조정 빈도보다 높아지도록 인버터(220) 및 커패시터를 제어한다.
