Abstract :The dual active bridge DC-DC converter topology gains developing application area in renewable energy systems, electric vehicles, power quality devices etc. due to its structural and functional advantages. In this paper, a new dual active bridge insert ignore into journalissuearticles values(DAB); based DC-DC converter equipped with an isolated high frequency transformer with 1 primary / 3 secondary windings is proposed which is composed of three voltage source converter insert ignore into journalissuearticles values(VSC); in the secondary side and a voltage source converter in the primary side. Each voltage source converters have own dc links.  The single phase shift modulation insert ignore into journalissuearticles values(SPS); method that is the commonly used control method in high power transfer applications is used for each voltage source converters independently to achieve bidirectional power flow of DC-DC converter. The phase shift modulation is implemented by PI controller. The power flow between the dc-links are provided by VSC’s own phase shift angles. Moreover extended phase shift insert ignore into journalissuearticles values(EPS); modulation and dual phase shift insert ignore into journalissuearticles values(DPS); modulation is also implemented to the system to control the power flow. Performance comparison of modulation methods is also done in the study. To validate the proposed system, a simulation model has been developed for 10 kVA rating using MATLAB/Simulink. The performance of the proposed system is verified with various case studies.
