Abstract :
The analysis and the technique of determining the cross-regulation characteristics in multioutput high-order series-resonant converters (SRCs) are presented. The steady-state cross-regulation characteristics are derived using the state-plane techniques, illustrated by the example of a two-output LLC-type SRC. A technique of minimizing the cross-regulation by compensating the differential rate of leakage fluxes in the multiple secondary windings of the isolation transformer is suggested. The theoretical results are verified by simulation
