A Novel Partial Power Cascaded DC/DC Topology for CPV Application: A Theoretical Study
Résumé
This paper presents a novel partial power DC/DC topology for CPV applications. The context of the CPV requirements is first derived in terms of losses factor, and compared to traditional centralized topology. An additional cascaded DC/DC stage is then proposed. It consists of Delta Power Converters used for current independence cascaded with Partial Power Converters for string voltage independence. The theoretical explanation and example using realistic shading pattern are presented. Last, the increased yielded energy provided by the complete cascaded topology is shown.
