Boost converters plays a crucial role in high power applications. They can be combined with a voltage doubler to have a better performance. The low output of a renewable energy sources is boosted to suitable voltage using boost converter and voltage doubler circuit. The proposed converter eliminates the limitations of the conventional converters and they have the advantages like interleaving structure, nonisolated structure and soft switching scheme. Due to soft switched scheme, the current stress and voltage stress are eliminated and hence reduced switch losses. Interleaving structure guarantees equal current sharing and hence reduced component size. Non-isolated structure reduces the circuit size and complexity. A 10 W converter is designed and simulated. A closed loop control method is adopted to overcome the voltage drift problem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
