WIRELESS INDUCTIVE ELECTRIC POWER TRANSMISSION Russian patent published in 2019 - IPC H02J5/00 H02J50/10 

FIELD: electrical engineering.

SUBSTANCE: transmitter (101) of electricity provides for the transmission of electricity to receiver (105) of electricity using wireless induction transmission of electricity. Electricity transmitter (101) comprises inductor (103) generating an induced carrier signal when the excitation voltage signal is applied. Measuring unit (311) measures the current and voltage of inductor (103). Measurements are made with a time shift relative to the reference signal synchronized with the excitation voltage signal. Adapter (313) can change the time shift to determine the optimal clocking shift of the measurements leading to the maximum demodulation depth for the modulation depth, which reflects the measure of the difference for the measurements at different modulation loads of the induced carrier signal. Then, demodulator (309) demodulates the modulation of the load of the induced carrier signal, obtained from the first measurements with the first shift, which is set equal to the optimal shift of the timing of the measurements. In some scenarios, it is possible to change both clocking and measurement duration.

EFFECT: technical result is to provide reliable communication with an increased distance between the coils of the power receiver and the power transmitter.
