Abstract
The increased demand of an intermediate
storage of electrical energy in battery systems, in
particular due to use of renewable energy, has
resulted in the need of dual active bridge converters
or bidirectional DC to DC power converters. The
most cost effective solution for electrical energy
storage is battery. The battery output is converted to
AC for connecting to electrical loads. Charging and
discharging of the battery can be carried out by
bidirectional power converters. DAB converter can be
used for battery charging and uninterruptable power
supply for hybrid vehicles, telecommunication,
industrial, space and defence applications. This thesis
investigates different isolated bidirectional DC–DC
converters with a rating of voltage 220V, frequency 1
kHz and power of 1600W. Closed loop control blocks
for various applications of DAB circuit have been
proposed and validated by simulation.
