INDUCTIVE CHARGING DEVICE, SYSTEM FOR INDUCTIVE ENERGY TRANSFER AND METHOD FOR GENERATING A CONTROL CURRENT

An inductive charging device includes an energy coil for wireless power transfer and a positioning device with a transmit coil for alignment detection. A control device generates a drive current for the transmit coil by producing an AC carrier signal, pulse shaping the signal into an amplitude-modulated AC signal via a pulse signal, and filtering the modulated signal to attenuate harmonics.
