Ultracapacitor selection and design for the Regenerative Breaking
PG student, Electrical Engineering, LDCE, Ahmedabad, India
ABSTRACT
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
