Analysis and design of a Current-Fed Dual Half-Bridge Converter

In this thesis the Current-Fed Dual-Half Bridge (CFDHB) converter has been presented and studied under three degrees of freedom. This is an isolated bidirectional converter useful in a lot of applications characterized by sources and/or loads that benefit from a smooth input/output current. A design methodology has been proposed which reduces the RMS current in all devices and guarantees the soft commutations of all switches in a wide range of operating points. Finally, simulation and experimental verification complete the work.
