DEVICE FOR TRANSMITTING ELECTRICAL ENERGY AT INDUSTRIAL FREQUENCY THROUGH CONDUCTIVE SCREEN Russian patent published in 2023 - IPC H02J50/12 H02J50/70 

FIELD: electrical engineering

SUBSTANCE: wireless transmission of electromagnetic energy through conductive screens at industrial frequency and can be used in wireless chargers, in power supply systems for devices located in partially or completely closed metal screens. A device for transmitting electrical energy at an industrial frequency through a conductive screen includes an electrical energy transmitter with a transmitting coil, an electrical energy receiver with a receiving coil, the novelty is that between the transmitting and receiving coils there is a conductive electrical current screen, the thickness of which is less than the depth of the skin layer in it for the given operating frequency, capacitors are connected in parallel to the transmitting and receiving coils, while the coils and capacitors form coupled oscillatory circuits, and transmission of electrical energy is carried out at one of the resonant frequencies, on which the difference between the phases of the currents flowing in the receiving and transmitting coils is in the range from 160° up to 180°.

EFFECT: possibility of transmitting electrical energy at an industrial frequency (50/60 Hz) through an electrically conductive screen.
