  Medium voltage direct-current based integrated power system is projected as
one of the solutions for powering the all-electric ship. It faces significant
challenges for accurately energizing advanced loads, especially the pulsed
power load, which can be rail gun, high power radar, and other state of art
equipment. Energy storage based on supercapacitors is proposed as a technique
for buffering the direct impact of pulsed power load on the power systems.
However, the high magnitude of charging current of the energy storage can pose
as a disturbance to both distribution and generation systems. This paper
presents a fast switching device based real time control system that can
achieve a desired balance between maintaining the required power quality and
fast charging the energy storage in required time. Test results are shown to
verify the performance of the proposed control algorithm.
