This paper presents an automotive suitable power electronics for inductive energy transfer of up to 22kW within a box volume of 3.51. The compact layout and an optimized system topology allow the realization of rectifier and reactive current compensation with a high efficiency of around 98%. The specific layout takes into account cooling of the resonance capacitors as well as of the rectifier. The automotive environment requires failsafe functionality which is independent of the wireless data transfer to the primary side. The hardware is dimensioned and prepared for realizing an additional secondary side power control. Thus, the optimal electrical working point of the energy transfer can be adjusted and overall system losses can be reduced.
