Abstract: PURPOSE: An energy storage apparatus for using different charging/discharging path, and an energy storage system thereof are provided to differently set up an electricity transmission path according to charge and discharge and to improve power efficiency. CONSTITUTION: A transformer(210) transforms the voltage inputted from input power. The transformer delivers electricity to a load through a first path. A charge and discharge part(220) is connected in parallel to the transformer. The charge and discharge part store the electricity output from the input power through a second path. The charge and discharge part deliver the electricity to the load through a third path.

Abstract: PURPOSE: An uninterruptible power supply controlling apparatus is provided to stably supply power by equally maintaining a control method of a system according to a system mode and an independent mode. CONSTITUTION: A transformer(210) transforms a voltage of power inputted from an input power source(100) and outputs the transformed voltage to a DC link. An inverter(220) transforms a voltage of the DC link into an AC voltage and outputs the AC voltage to an output terminal connected to a load. A charging and discharging unit(230) charges or discharges the input power. A control unit(240) constantly maintains the voltage of the DC link and controls a voltage of the output terminal through the charging and discharging unit when a power outage occurs in the output terminal.
