Life Interactive UPS Systems
The block diagram of lien integrative UPS is shown in figure when the main supply is ON static switch remains closed and load is connected to mains through an inductance L. In this condition the battery bank the DC through inverter which is used in as charger now.
Under the condition of power failure the main static switch becomes open. In this condition the battery bank supplies the power to the load through the inverter.
