<p>The circuit device has a power receiver (12) and a power transmitter (10) that has a driving device (14) for driving electronic switches (T1,T2) with drive signals. The power transmission side resonance circuit comprises a power transmission-side capacitor (CPS) and a power transmission-side impedance (LP) which are mutually connected in series. An evaluation device (16) is coupled with power transmission-side capacitor or impedance, for evaluating resonance current of resonance circuit. An impedance modulation device (18) is coupled to a receiver-side power coil (LS).</p> |
