Abstract
Efficient energy storage system is one of the most vital elements in a DC
micro gird. The efficient of the energy storage system mainly depends on
the converter that is used. Therefore, it is very important to achieve the
high efficiency during power conversion process. This project focuses on
the design of a bidirectional DC-DC converter for a battery charging
system which will be used in DC micro gird. The interleaving topology
is explored and discussed in this project to improve efficiency, reduce
ripple and shrink the size of capacitors and inductors in DC-DC
converter. The closed loop control of multiphase interleaved DC-DC
converter is implemented in the MATLAB Simulink software. The
average current control loop system will be discussed to observe the
simulation results. Moreover, the phase shedding technique will also be
introduced to improve the efficiency of the DC-DC converter while
operating at light load situation.
