“…There have been various non-isolated type converter topologies implemented under softswitching condition. A passive lossless bidirectional converter [28] was operated with ZVS for the applications of electromechanical braking systems in electric vehicles. It is operated at very low input voltage, low power and low switching frequency.…”

This paper presents a dual inductor based current-fed bidirectional non-isolated DC-DC converter for energy storage applications. The main idea of this converter is to achieve a higher voltage conversion ratio by obtaining the operation of zero current switching. The proposed soft-switching bidirectional DC-DC converter reduces the turn-off switching losses with the aid of auxiliary network, where, the auxiliary network comprised with the resonant inductor and the resonant capacitor. This converter operates under two different operating modes such as a boost (discharge) and buck (charge) modes. In both the modes of converter operations, the IGBTs are operating under zero current turn-off in order to minimize the switch turn-off losses and to improve the efficiency of the converter. The principle of the operations and its theoretical analysis are validated by the experimental results using a 300W (50 V/250 V) converter system.
