PROBLEM TO BE SOLVED: To provide a push-pull power converter, self-driven by an output current of a power converter. SOLUTION: The push-pull power converter uses a main power supply transformer connected in series to a current transformer. A primary side of a current driven transformer gets feedback from a secondary electric current that flows via a secondary side of two transformers, thus generating a current for driving two switches. The drive current is directly proportional to a secondary current at secondary side of the main power supply transformer. COPYRIGHT: (C)2008,JPO&INPIT
