“MINI UPS SYSTEM” (AC Fan)
This is a non microocntroller based project related to EEE

AIM: The project aims in designing a mini UPS system that can be used to run the electric load (exhaust fan) when the mains supply is OFF.

Blocks: 230 v AC power supply, charging circuit, sensing circuit using comparator, battery (12 V DC), switch, load(AC FAN).

Working: Our project “Mini UPS System” is mainly intended to design a mini UPS system. This project uses comparator IC (LM358) to detect the over load, an inverter for DC to AC conversion, charging on and battery low conditions. CFL loads are suggested for this project, as they consume low power and produce high intensity of lighting.
A rechargeable 12V battery is used to store the energy during power availability. The back up time depends on the battery ampere — hour rating. This inverter can show the battery low condition and over conditions by 5mm LED indicator circuit.
The battery is connected to the inverter. This inverter is used to convert the 12volt DC to the 230 Volt AC. This 230 volt AC voltage is used to activate the loads. Here we are also using conventional battery charger unit to recharge the battery. In this project we are using regulated 5v, 750mA power supply for micro controller unit. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the AC output of secondary of 230/12v step down transformer.

Advantages:
1. This system helps in providing uninterrupted power supply.
2. Usage of rechargeable battery.
3. Inverter circuit design
4. Efficient and low cost design.
5. Easy to operate.
6. These inverters play vital role especially in rural area
