Abstract
Off-line power supplies for consumer or industrial electronics frequently encounter substantial changes in both input voltage range and load current requirement. This study presents theoretical and practical details involved with the dynamic analysis and control design of LLC series resonant dc-to-dc converters operating under wide input and load variations. The accuracy of dynamic analysis and validity of control design are confirmed with both computer simulations and experimental measurements.Keywords
