A Battery/Supercapacitor Hybrid Combination in Uninterruptible Power Supply (UPS)

This study presents a design of internal parameters of supercapacitor using charging/discharging characteristics of a battery. We aim at investigating the optimal supercapacitors-battery combination .This investigation is twofold first, supercapacitors and battery models are developed using MATLAB/Simulink and are presented and. Second, the architecture and the simulation of the designed system that combines the Supercapacitor and the battery are shown. The supercapacitors are used as high-power storage devices to smooth the peak power applied to the battery during backup time and to deliver full load power during short grid failures. By charging the supercapacitor through the battery at a suitable rate, all impulse power demands would be satisfied by the supercapacitors. Citation: Gaurav R.
