  "textContent": "A non-contact power transmitting and receiving system includes an inverter (1) configured to generate a high-frequency voltage, a voltage-current sensor (12) configured to detect a phase difference between an output voltage and an output current of the inverter (1), a power transmission coil (21) connected to the inverter (1), a power reception coil (22) configured to receive electric power from the power transmission coil (21) in a contactless manner, a rectifier circuit (4) connected to the power reception coil (22), and a control unit (5, 6) configured to control the inverter (1) and the rectifier circuit (4). The inverter (1) includes arms (1A, 1B). The rectifier circuit (4) includes arms (4A, 4B). The control unit (5, 6) adjusts at least one of switching timing of any arm (1B) of the inverter (1) and switching timing of any arm (4B) of the rectifier circuit (4), in accordance with the phase difference detected by the voltage-current sensor (12).",
