Abstract
A converter circuit has a first resonant converter that is connected on the DC voltage side to a first energy storage circuit, and a transformer. A second resonant converter is connected on the AC voltage side to the secondary winding of the transformer and on the DC voltage side to a load converter, and a CLL resonant circuit is connected to the first resonant converter and to the primary winding of the transformer. The CLL resonant circuit has a resonant capacitance, a first resonant inductance and a second resonant inductance.
