Abstract

This paper presents the analysis and the technique of determining the cross regulation characteristics in multioutput resonant converters. The steady state cross regulation characteristics are derived using the state-plane technique, illustrated by the example of a two-output clamped series resonant converter (SRC) operating in the discontinuous conduction mode below resonance. The cross regulation characteristics in conjunction with the control curves can be used to determine the converter operation for optimum performance. The theoretical prediction of converter operation and cross regulation characteristics in a two-output power supply is verified experimentally. This technique can be applied to most converters with more than two outputs
