A circuit configuration contains a resonant converter feeding energy into a primary winding of a transformer, a control circuit for controlling the resonant converter and a plurality of modules. The modules include a frequency generator controllable with variable frequency, a short circuit monitoring unit configured to protect components of the resonant converter, and an open circuit detection unit. The open circuit detection unit is configured to shut down the resonant converter if a secondary side interacting with the primary winding of the transformer is open circuit, without having information from the secondary side.
