Özet
This paper addresses the modeling and analysis of a new bidirectional isolated dc-dc converter (BIDC) based on a multilevel inverter topology. The novelty of the study is the utilization of the reduced switch five-level inverter topology instead of the conventional full-bridge dual active bridge. It has the advantage of lower voltage/current stress on the switches at higher voltages as compared to traditional BIDCs. Power transfer between primary and secondary sides is controlled by PI controller-based single phase shift (SPS) modulation technique. The proposed converter stands out for having: i) employing a reduced number of switches compared to other multilevel inverter-based bidirectional dc-dc converter topologies ii) high voltage gain iii) low harmonic level iv) suitable for integrating multiple input multiple output electrical systems and to be used in bipolar dc microgrid applications. In order to validate the performance of the proposed converter, a simulation model has been developed in Matlab/Simulink environment. The performance of the suggested converter and the controller scheme under steady-state and dynamic conditions have been revealed through the simulation results. © 2022 IEEE.
