This paper will present several topologies that lead to a better utilization of transformer’s magnetic core. In these topologies the main transformer becomes a magnetic storage element, reducing the size of the output filter. Quasi-integrated magnetic will be presented as an intermediate step between conventional and fully integrated magnetic underlying its advantages and limitations. There will be presented quasi-integrated magnetic topologies with and without secondary winding tap. Two methods of eliminating the secondary winding tap will be suggested, one by using current-doubler and the second by employing two symmetrical transformers. Two 100W 5V@20A experimental converters were built and evaluated using quasi-integrated magnetic under two different implementations.
