  "textContent": "An inductive coupled power transmission circuit has a rotating transformer, comprising an AC voltage supply for feeding an AC voltage via a series capacitor into the primary winding of said rotating transformer and a load being coupled to the secondary winding of said rotating transformer. The AC voltage supply comprises a line rectifier for receiving AC voltage from a power line and generating a DC voltage. This is fed into a DC/DC converter for converting the DC voltage from the line rectifier into a controlled intermediate DC voltage. An AC generator generates an AC voltage from the intermediate DC voltage and feeds this via a matching transformer into the primary winding of the rotating transformer. A measuring circuit measures voltages and/or currents within the AC voltage supply and a function generator estimates voltage and/or current values at the load based on the measured values and controls the DC/DC converter and/or the AC generator based on the estimated values.",
