Patent ID: 7956491

Claim:
An integrated multi-transformer, comprising: a core made of magnetic material; a plurality of transformers magnetically coupled with the core, including: a pulse transformer comprising a first primary winding and a first secondary winding, the first primary winding being configured to receive a first primary current and to couple the first primary current to the core to generate a first core flux, and the first secondary winding being configured so that at least a portion of the first core flux is coupled from the core to induce a first secondary current in the first secondary winding; and a power transformer comprising a second primary winding and a second secondary winding, the second primary winding being configured to receive a second primary current and to couple the second primary current to the core to generate a second core flux, and the second secondary winding being configured so that at least a portion of the second core flux is coupled from the core to induce a second secondary current in the second secondary winding, wherein the first core flux induces substantially no current in the power transformer and the second core flux induces substantially no current in the pulse transformer.
