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...

The arrangement has a coil (10) i.e. pneumatic winding, spatially arranged between other two coils (16, 20). A fixing device (30) fixes the three coils in a concentric direction relative to each other for inductive energy transfer. A power supply device is...
