CONTACTLESS POWER TRANSMISSION SYSTEM FOR VEHICLE DOORS Russian patent published in 2019 - IPC B60L1/00 H02J50/12 

FIELD: electrical engineering.

SUBSTANCE: invention relates to wireless transmission of electric power to vehicle doors. Proposed system comprises frame and flap, transmitter unit and receiver unit. Transmitter unit is connected to the frame and comprises a power supply and an oscillatory circuit. Receiver unit is connected to the flap and to the working system unit and comprises an oscillatory circuit. Vibratory circuit of transmitter unit and oscillatory circuit of receiver unit are tuned for operation in resonance mode. Transmitter unit comprises a square-wave generator, a frequency-automatic tuning unit and a power amplifier. Receiver unit is connected to the working system unit via the diode bridge and additionally connected to the energy accumulator. At that, as coils of oscillatory circuits of transmitter unit and receiver unit flat inductors are used, which reverse sides are screened by material from ferromagnetic material, either coils on cup-shaped core from ferromagnetic material, or combination of coil on cup core and flat inductance coil is used.

EFFECT: technical result consists in increase in electric power transmission distance.
