Abstract

A novel two-phase interleaved soft-switching bidirectional DC-DC converter is proposed. The soft-switching auxiliary circuit of the converter is composed of an inductor and a capacitor in series. The auxiliary circuit can not only realize the sharing between two phases, but also work only once in a cycle. This paper presents the topological structure and soft-switching operating principles of the converter; analyzes the key waveforms under different duty cycles and the conditions for achieving soft-switching; proposes a full range soft-switching modulation method based on peak-valley value detection; and performs topology deduction. Finally, a 250 W experimental prototype is built for verification. The experimental results show that all the switches of the converter can achieve zero-voltage switching, and the peak efficiency can reach 99.38%.
