WIRELESS INDUCTIVE POWER TRANSMISSION Russian patent published in 2019 - IPC H02J50/12 

FIELD: electrical engineering.

SUBSTANCE: according to invention transmitter (101) of capacity of wireless power transfer system contains resonant circuit, which includes coil (103) of transmitter for generation of signal of power transfer for transfer of power wirelessly to power receiver (105). Besides, excitation device (1303) generates excitation signal for resonance circuit (201), and receiver (1305) of messages is made with possibility to receive message from power receiver (105). Power loop controller (1307) realizes the power control loop by tuning the excitation signal power in response to the power control messages received from power receiver (105). However, control is applied taking into account limitation of at least one of current or voltage of resonance circuit, as well as power of excitation signal, so that they are below maximum limit. Besides, power transmitter (101) comprises adjustment device (1309), which adjusts maximum limit in response to load indication, which shows loading of power transmission signal by power receiver (105).

EFFECT: technical result consists in improvement of wireless transmission power reliability.
