Increasing gap between power supply and demand causes electricity crisis and excessive load shedding in any developing countries like Pakistan as well as the power failure due to numerous reasons. Therefore, in such circumstances a short-term and best solution for users in terms of instant and back up supply can be through Uninterruptible Power Supply (UPS) it could be more effective and efficient with hybrid storage source and active power filter. Moreover, the growing trend in U.P.S industry has been observed because it delivers a continuous and clean power supply to critical and sensitive loads without delay or transients it also offers instant protection when utility power is not available. However, in this manuscript authors discussed brief look regarding UPS types, control techniques and reliability and also investigate the optimal power transfer for sustainable power source including minimizes the total harmonic distortion (THD) from 46 % to 1.46 % with proposed active power filter (APF), in order to save more than 15 % energy during conversion.
