Circuit for a system for a contactless, inductive energy transfer

The circuit has a primary-sided circuit arranged on a primary side and connected with a primary-sided supply voltage. A secondary-sided circuit is connected with a load and includes an after-stabilization stage i.e. linear regulator. A transmission stage includes a resonant converter and a galvanic separation for contactless transmission of energy from the primary side over an air gap away from the secondary side. Two magnetically coupled coils are provided for inductive energy transmission and spatially separable from each other by separating the secondary side from the primary side.
