Lead acid battery, super capacitor, uninterruptible power supply (UPS).


This report presents a study of reduction in battery stresses by using super capacitor (SC) in a 500 kVA rated uninterrupted power supply (UPS).In this investigation first, Super Capacitor model developed using MATLAB/Simulink is present and validated. Second, the architecture of the designed system that combines the Super Capacitor and Battery are shown. The Super capacitors are used as high power storage device to smooth the peak power applied to the battery during back up time and deliver full power during short grid outage. By charging SCs through battery at suitable rate, all impulse power demand would be satisfied by the SCs.
