dc.description.abstractA Novel, transformer-less, bidirectional DC-DC Converter based on modified SEPIC topology is proposed in this paper. In the proposed converter, an active switched inductor configuration is incorporated in the conventional SEPIC converter to achieve a wide voltage conversion ratio with reduced voltage and current stress across the components. The proposed converter supports bidirectional buck-boost (BBB) capability with low components. The proposed converter's operating principle and steady-state analysis are explained in detail for continuous conduction mode (CCM). Dynamic modelling of the converter is presented and closed-loop controllers are designed. The proposed converter operates in both current and voltage control modes. The design of voltage and current compensators are detailed in this paper. Detailed analysis and simulation results are presented to validate the theoretical analysis and performance of the proposed converter. © 2023 IEEE.
