In an embodiment a method for operating a wireless charger includes providing a set of parameter records, assigning parameter records of the set of parameter records to individual converters and generating and providing, for each converter depending on an assigned parameter record, a control signal vector so that a multi-level converter arrangement including the converters provides a supply power with a desired signal waveform to a power source resonator, wherein the parameter records depend on the desired signal waveform of the multi-level converter arrangement, wherein each parameter record defines a duty-cycle and/or a phase shift angle of the converter output signal, and wherein the duty-cycles and/or the phase shift angles of at least two parameter records are different.
