Abstract
The invention relates to a combined transformer for an LLC resonant converter. The combined transformer includes a primary transformer winding configured to generate during operation a first magnetic flux, which forms a first magnetic circuit. The combined transformer also includes a resonant inductor having a winding, wherein the resonant inductor is configured to generate during operation a second magnetic flux, which forms a second magnetic circuit. The primary transformer winding and the winding of the resonant inductor are arranged with respect to one another such that at least one first part of the first magnetic circuit and at least one second part of the second magnetic circuit run on a magnetic path common to the first part and to the second part. The invention also relates to an LLC resonant converter with such a combined transformer.
