Design And Construction Of A 3KVA Uninterruptible Power Supply Using SG3524N
The purpose of this project is to design and construct an uninterruptible power supply. Uninterruptible power supply is a voltage regulatory and uninterruptible power device planned to electromechanically sustain a constant voltage level and supply an uninterruptible power to devices.
This device receive minimum voltage of 120vac and maximum of 260vac and filter the current and voltage thereby brings out suitable voltage output to be used by the devices in it, then when there an unexpected power outage from the utility mains or generator the system will automatically switch over to the inverter source thereby providing additional power to the appliances in use without interruption.
This device stabilizes an AC input voltage of 120-260V to give an AC output voltage of 240V, provide a rechargeable backup power supply the system and also provide low battery indication automatically. The automatic feature can be achieved by the electronics devices used such SG3524N IC, electro-magnetic device (relay), auto- transformer and other electronics devices.
