Abstract
Cross regulation is a technique for providing multiple regulated output voltages from an energystorage dc-to-dc converter where only one of the outputs is actually sensed by the controller and regulated to the desired value. The regulation of the remaining output voltages depends on the magnetic coupling between the multiple secondary windings of the energy-storage transformer. This paper extends the analysis of [l] by examining the cross regulation performance of a two-output voltage step-up/current step-up dc-to-dc converter operating in the continuous mmf mode under constant-frequency control. The analysis is shown to be a useful tool for generating test specifications for screening energy-storage transformers to guarantee that the leakage flux associated with the transformers does not prevent the converter from providing adequate cross regulation.Keywords
