Abstract
A primary unit for an inductive charging system includes a primary coil, which is configured to generate a magnetic field in response to a coil current through the primary coil; a first inverter, which is coupled to the primary coil via a first capacitor and which is configured to charge and/or discharge the first capacitor based on a first input voltage; and a second inverter, which is coupled to the primary coil via a second capacitor and which is configured to charge and/or discharge the second capacitor based on a second input voltage. The primary unit has a control unit, which is configured to identify capacitance information with respect to an effective capacitance of a primary resonant circuit of the primary unit, and to actuate the first inverter and the second inverter depending on the capacitance information in order to effect the coil current through the primary coil.
