Abstract

This paper proposes the hybrid UPS(Uninterruptible Power Supply) with ESS(Energy Storage System) function. The proposed hybrid UPS is operating in four states, which are normal state, battery state, ESS state, and bypass state. In case of peak load time or power shortage, the system is operating in ESS state in which the stored energy of the battery is used to manage the power effectively. The validity of proposed system are verified by simulations and experiments.
