<p>The transmission circuitry comprises a power transmitter (10) and a power receiver (12), in which the power transmitter has input terminals (E1,E2), and a bridge circuit having two electronic switches (T1,T2) which are coupled in series between the two input terminals. A bridge center point (BM1) is formed between the electronic switches. A control device (20) is designed to detect the reach of an output voltage (Vo) to the upper limit value, through a monitoring device (22), to recharge a recipient-side capacitor (C-SS) to a predetermined voltage or to the output voltage. The transmission circuitry comprises a power transmitter and a power receiver, in which the power transmitter has input terminals, and a bridge circuit having two electronic switches which are coupled in series between the two input terminals. A bridge center point is formed between the electronic switches. A driving device (14) is arranged for driving the electronic switches with the drive signals (A-S1,A-S2). A power transmission side resonance circuit is comprised of a power transmission-side capacitor (C-PS) and a power transmission-side inductor (L-P) mutually connected in series. The resonance circuit is coupled between the bridge center point and one of the two input terminals. The power receiver is comprised of a power-reception-side resonant circuit, a recipient-side capacitor and a power-receiver coil (L-S). The power-receiver coil and the power transmission-side inductor are inductively coupled to provide an output having two output terminals (A1,A2) for providing an output voltage to a load (RL). A control device is adapted for turning-off the electronic switches, if the output voltage reaches the upper limit value. The electronic switches are switched-on, when the output voltage reaches the lower limit value. The power receiver is coupled to the monitoring device. The control device is designed to detect the reach of output voltage to upper limit value, through the monitoring device, to recharge the recipient-side capacitor to a predetermined voltage or to the output voltage. An independent claim is included for an inductive energy transmission method.</p> |
