Abstract

The invention relates to a resonant converter (1) which has multiple outputs (7a, 7b) and contains a transformer (4) with a primary winding (5) and at least two secondary windings (6a, 6b) having different winding directions. In this way it is possible to design as cost-effectively as possible a resonant converter with multiple outputs, two of which can be controlled separately from each other.
