Abstract

The transformer has a magnetic circuit consisting of a first core part (1) carrying a primary and a secondary winding (4) and closed by further core parts (2) and at least two isolators (3) for electrical insulation between the primary and secondary sides of the transformer. The first and further core parts are arranged so that a higher flux density arises in the first core part than in the other core parts.
