Abstract :
Current sharing is an important issue in both isolated and non-isolated dc-dc converters. In the paper, average current sharing is modeled and analyzed for isolated dc-dc converters with current doubler rectifier. Important design guidelines and conclusions are provided based on the mathematical modeling and analysis. A modified current doubler rectification is presented to achieve balanced current sharing between two inductors of current doubler rectifier in the half bridge dc-dc converter. Experimental results are presented to verify the analysis and proposed topologies
