Abstract

A wireless charging system with a feedback loop which includes on the supply side a high-frequency generator, whose input is connected to the controlling output of a controller, and whose output is connected to the first input of a modulator whose input is connected to an antenna and to the input of a decoder whose output is connected via an amplifier to the input of the controller, and the data output is connected to the second input of the modulator, and, on the side of the charging unit, another antenna connected to the output of the modulator and to the inputs of a decoder and an inverter, whose outputs are connected respectively to the data and energy inputs of the charge-discharge controller which is connected to a storage battery and/or to an supercapacitor unit, the data and the controlling outputs of the charge-discharge controller being connected respectively to the first input of the modulator and to the input of the generator, whose output is connected to the second input of the modulator, wherein the inverter includes a rectifier and a voltage multiplier connected in series.
