This paper presents a study of the reduction in battery stresses by using Super capacitors (SCs) in UPS. We
aim at investigating the optimal Super capacitors-battery combination versus the SCs cost. This investigation is threefold;
first, super capacitors and battery models developed using MATLAB/ Simulink are presented and validated. Second, the
architecture and the simulation of the designed system that combines the SCs and the battery are shown. The Super
capacitors are used as high-power storage devices to smooth the peak power applied to the battery during backup time
and to deliver full power during short grid outages. By charging the SCs through the battery at a suitable rate, all impulse
power demands would be satisfied by the Super capacitors. Third, extensive simulations are carried out to determine the
gain in battery RMS current, the gain in energy losses, the energy efficiency and the elimination rate of surge load power.
These four performance parameters are determined by simulation and then analyzed.

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
