  "textContent": "The invention relates to an inductive charging device (1) for charging an electrical energy storage device (3) of a vehicle (2), comprising a primary coil (4) and an inverter (5) upstream of the primary coil (4) for converting a direct voltage into an alternating voltage, wherein the inverter (5) comprises a direct voltage input (6) and an alternating voltage output (7) and wherein at least one switch stage (8, 9) and at least one filter (13) are connected between the direct voltage input (6) and the alternating voltage output (7). In order to generate an alternating voltage that is as sinusoidal as possible without harmonics, wherein the efficiency of power transmission should not be impaired, the filter (13) comprises a leakage field transformer (10) with a first winding section (11) and a second winding section (12).",
