IEEE;IEEE Computational Intelligence Society;IEEE Instrumentation and Measurement Society2016 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications, CIVEMSA 2016 --27 July 2016 through 29 July 2016 -- --In this study, operation, design and comparison of Dual Phase-Shift and Novel Fuzzy Logic control methods on isolated bidirectional DC-DC converter are discussed. The major components (DC link capacitors and inductors) are created for dual phase shifting method in order to obtain maximum efficiency. Triggering signals, voltage-current waveforms are compared and efficiencies are listed for all of these control methods at buck and boost modes of the full-bridge converter topology without using snubber capacitors to reduce cost feasibility. The main contribution of this paper, applying one of the most common used phase-shift control method, dual phase-shift and comparing with proposed novel Fuzzy Logic control method (Fuzzy-PSO-PI) on efficiency way for medium voltage applications. In this paper, isolated bidirectional DC-DC converter topology is modelled and control algorithms are written by FORTRAN programming language. © 2016 IEEE
