WIRELESS SYSTEM OF ELECTRIC POWER SUPPLY AND ELECTRIC POWER TRANSMISSION DEVICE Russian patent published in 2017 - IPC H02J50/10 

FIELD: electricity.

SUBSTANCE: wireless power supply system comprises an electric power transmission device (10) provided on the ground side and an electric power receiving device (20) mounted on the vehicle, the electric power transmission device (10) transmits the electric power controlled by an inverter circuit (12) to the electric power receiving device (20) via a wireless connection. The electric power receiving device (20) transmits the control signal of electric power supply to the electric power transmission device (10) in the first cycle by means of a radio signal. The electric power transmission device (10) includes means for determining the current of the electric power transmission coil for detecting the current of the electric power transmission coil flowing through the electric power transmission coil (13) and controls the output voltage of the inverter circuit (12) based on the command signal of electric power and current supply of the electric power transmission coil determined by the means for determining the current of the electric power transmission coil in the second cycle, which is shorter than the first cycle.

EFFECT: ensuring reliable transmission of energy in the event of situational changes.
