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 (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 (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 (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
(EPS) modulation and dual phase shift (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.
