Due to the several advantages of the electrochemical double layer capacitor (EDLC) also called the
ultracapacitor over the Electrochemical Batteries it is intensively used in the Regenerative Energy Recovery system in
the modern controlled electrical drives. Where ultracapacitor can fully charge and discharge in few number no of
seconds also it can be served as a short-term UPS during the power interruption condition. In this paper complete
selection and design guideline for the selection of the ultracapacitor module. Selection of the mail parameters such as
capacitance, voltage rating, and efficiency, number of series or parallel connected cells, conversion losses are
discussed. At the end of the paper the design example of the practical drive is presented
