Abstract
The invention relates to a method of operating a three phase primary winding structure of a system for inductive power transfer, wherein the primary winding structure includes a first phase line, a second phase line and a third phase line, wherein in a standard operational mode a first phase input voltage, a second phase input voltage and a third phase input voltage are controlled such that a predetermined phase shift between all three phase input voltages is provided, wherein in a modified operational mode the first phase input voltage, the second phase input voltage and the third phase input voltage are controlled such that the set of phase shift values includes at most two non-zero values and all non-zero phase shift values are equal. Furthermore, the invention relates to a primary unit of a system for inductive power transfer.
