2. SCOPE
To design a less expensive and high efficiency inverter
Adoptable for Economically disadvantage peoples
3. ABSTRACT
Inverter crude form of an UPS
Amplifying Section is done with the help of Transistors
Oscillator is used to invert DC voltage to AC voltage
Transformer is used to provide high output current
4. FURTHER TECHNOLOGIES
Inverter using Microcontroller and Solar Panel
High Cost
High Maintenance
Occupying more space
Required more components
5. PROPOUND TECHNOLOGY
We proposed Inverter which is in-expensive and high
efficiency.
IC 4049, Oscillator is used for an Oscillating section
Applied Oscillating signal is stepped up by using step-
up-transformer
The battery charger is used to charge the battery when
AC main is restored
8. IC 4049 Oscillator
For generating large magnitude of Alternating voltage
from Stored Direct Voltage
It is a voltage doubler
It uses less energy
9. Transistor
Transistor is used as amplifier
TIP127 is general purpose amplifier & Low speed
switching transistor
RCA40411 transistor act as an amplifier and switch
10. TRANSFORMER
A transformer is an electrical device that transfers
energy between two circuits through electro
magnetic induction
It is used as safe and efficient Voltage converter
12. CIRCUIT DESCRIPTION
N1&N2 is an Oscillator performs the primary function
of supplying square wave
Gate N3 to N6 act as buffer. Output of buffer is applied
to base of the transistors T1&T2
Output of T1&T2 is given to the transistor T3&T4.
It deliver the entire voltage to the transformer and it
stepped up to 230V AC
14. GAIN
Low Cost
High Efficient
Easy Maintenance
Occupying less space

16. LITERATURE REVIEW
• According to paper[1] and paper[2] uses microcontroller, it is
high cost, difficult to assemble, Heavy weight, required more
components
• On the other hand paper [3], the 100’s of inverters are connected
to the main system via the LAN connection In this lot of Cables
are required, High Cost, Occupying more space, It need human
interaction for monitoring the inverters
17. CONCLUTION
By this method underprivileged can get electricity during
mains off
Less weight, maintenance free inverter it’s very useful in
