The invention relates to a method for operating an inductive charging device (1) comprising two inductors (11, 12) and two switching stages (8, 9) connected thereto. In order to achieve a stationary operational state, said switching stages (8, 9) are each controlled with a periodic signal of the same frequency, and the switching phase shift is reduced/increased proceeding from a starting value until it reaches a predefined value or until a perceptible output current (IA) is obtained. The switching frequency is then reduced/increased so as to reach a desired phase shift between output current (IA) and output voltage(UA) or output power. Once transient processes have subsided, the switching phase shift is reduced/increased further until the output power reaches a predefinable target value. The invention also relates to a control system (27) for carrying out said method, and to an inductive charging device (1) comprising such a control system (27). |
