A converter system comprising:
- a first primary-side bridge;
- a first secondary-side bridge;
- a second secondary-side bridge;
- and
- a transformer with a first winding pair comprising a first primary-side winding and a first secondary-side winding, and a second winding pair comprising a second primary-side winding and a second secondary-side winding;
- wherein the first primary-side winding and the second primary-side winding are connected in parallel with the first primary-side bridge;
- wherein the first secondary-side winding is connected to the first secondary-side bridge;
- wherein the second secondary-side winding is connected to the second secondary-side bridge;
- wherein the first winding pair is positioned in an axial direction relative to the second winding pair, wherein the axial direction extends along a leg of a core of the transformer;
- and
- wherein the first primary-side winding and the first secondary-side winding are concentrically arranged around a same first position along an axis of a core of the transformer, and wherein the second primary-side winding and the second secondary-side winding are concentrically arranged around a same second position along the axis of the core of the transformer, wherein the axis extends along a leg of the core of the transformer.
A method of producing a converter system comprising:
- providing a first primary-side bridge;
- providing a first secondary-side bridge;
- providing a second secondary-side bridge;
- and
- providing a transformer with a first winding pair comprising a first primary-side winding and a first secondary-side winding, and a second winding pair comprising a second primary-side winding and a second secondary-side winding;
- wherein the first primary-side winding and the second primary-side winding are connected in parallel with the first primary-side bridge;
- wherein the first secondary-side winding is connected to the first secondary-side bridge;
- wherein the second secondary-side winding is connected to the second secondary-side bridge;
- wherein the first winding pair is positioned in an axial direction relative to the second winding pair, wherein the axial direction extends along a leg of a core of the transformer;
- and
- wherein the first primary-side winding and the first secondary-side winding are concentrically arranged around a same first position along an axis of a core of the transformer, and wherein the second primary-side winding and the second secondary-side winding are concentrically arranged around a same second position along the axis of the core of the transformer, wherein the axis extends along a leg of the core of the transformer.
