Abstract:The paper proposes an improved transformer with an integrated magnetic circuit of the push–pull converter. For high-power server-type applications, the push–pull forward converter has been proven to have significantly better performance than the buck converter. This topology also provides a built-in input filter, and thus a smooth input current. All the magnetic components are integrated in a single core. The simulation of integrated magnetic and magnetic-circuit analysis identifies the proposed transformer correctly. Comparison is given of experimental results of discrete and integrated transformers.
