摘要：This paper proposes a novel cascaded DC-DC boost converter aimed for PV applications. It consists of a conventional boost unit and a voltage multiplier network. The proposed configuration greatly enhances voltage gain while operating at low duty cycles. The extensive analysis is performed for the proposed converter in continuous current mode (CCM) and discontinuous current mode (DCM). Moreover, critical values of inductors are determined to investigate the boundary conditions between CCM and DCM. It was firmly concluded that while considering the lesser number of elements and semiconductor devices for the same input voltage, the proposed converter can yield comparatively high voltage gain than the conventional and recent boost dc-dc converters. Finally, the desired validation of the mathematical expressions is inspected via simulation results
