Abstract :
This paper presents an uninterruptible power supply capable of proving power for several seconds. Ultracapacitors are used as the storage method since they are suitable for pulse power applications and longer life time. Selection of ultracapacitors and controller design for associated power electronic converters are presented in this paper. Further simulation results of the proposed uninterruptible power supply are also included in the paper.
