Abstract
A controller circuit is specified, having a step-up controller, a resonant converter connected downstream of the step-up controller on the output side, a transformer, a rectifier, which rectifier is connected to the secondary winding of the transformer on the input side, and a CLL resonant circuit connected to the resonant converter and to the primary winding of the transformer, which CLL resonant circuit has a resonance capacitance and a first and a second resonance inductance. In order to reduce the switching losses, the CLL resonant circuit is embodied as a “T” circuit.

A controller circuit having a step-up controller, having a resonant converter connected downstream of the step-up controller on the output side, having a transformer, having a rectifier, which rectifier is connected to the secondary winding of the transformer on the input side, and having a CLL resonant circuit connected to the resonant converter and to the primary winding of the transformer, which CLL resonant circuit has a resonance capacitance and a first and a second resonance inductance, wherein
- the resonance capacitance is connected in series with the first resonance inductance, the first resonance inductance being connected to a first connection point of the primary winding of the transformer and the resonance capacitance being connected to the resonant converter, and
- wherein the second resonance inductance is connected to the junction point between the resonance capacitance and the first resonance inductance, the second resonance inductance being connected to a second connection point of the primary winding of the transformer and the second connection point of the primary winding of the transformer being connected to the resonant converter.
