Abstract :
A new LLC resonant converter is proposed for front end DC/DC conversion in a distributed power system. This converter shows some potential benefits in this application. This paper proposes several integrated magnetic designs for LLC resonant converter. This converter has three magnetic components. With magnetic integration, first, a number of components can be reduced; secondly, flux ripple cancellation is achieved so that core loss is reduced. From these benefits, higher power density can be achieved. In design of the integrated magnetic structure for LLC resonant converter, a general model of four winding integrated magnetic structure is derived which can be used to derive integrated magnetic structure for different topologies. Finally, the test result is shown
