Abstract (en)

[origin: WO2004040600A1] The invention relates to a transformer including a first (1), a second (2) and a third (3) leg which are aligned in parallel and are magnetically connected, having at least a first primary winding (4) and at least two secondary windings (5, 6). Each of the windings are carried by a different leg, whereby the legs are arranged in a sequence and one of the secondary windings is located between the other two legs. The two legs are connected with a capacity (7) and thus form a resonance circuit. The magnetic connection between the two secondary windings differs from the magnetic connections between the primary and each of the secondary connections. The flux excited by the first secondary winding is anti-parallel to the flux excited by produced by the second secondary winding. A supply voltage can be supplied at the primary winding and the transformer provides a current and a voltage at the secondary windings.
