DETERMINATION AND MINIMIZATION OF CROSS REGULATION IN MULTI-OUTPUT HIGH ORDER SRC

This paper presents the analysis and the technique of determining the cross regulation characteristics in multi-output high order Series Resonant Converters. The steady state cross regulation characteristics are derived using the state-plane techniques, illus-aated by the example of a two-output LLC type SRC. It also suggests a technique of minimizing the cross regulation by com-pensating the differential rate of leakage fluxes in the multiple secondary windings of the isolation transformer. Our theoretical results are verified by simulation. I
