Introduction: How to Make 1.5V DC to 220V AC Inverter

About: HI! I am Junez Riyaz, currently doing Bachelor of Technology in the field of Electronics and Communication Engineering. I am much interested in inventing something new yet from my childhood. In my leisure ti...

Hello guys, In this Instructable I will instruct you to make your own 1.5v DC to 220v AC inverter with less number of components.

Inverters are often needed at places where it is not possible to get AC supply from the Mains. An inverter circuit is used to convert the DC power to AC power. Inverters can be of two types True/pure sine wave inverters and quasi or modified inverters. These true /pure sine wave inverters are costly ,while modified or quasi inverters are inexpensive.
These modified inverters produce a square wave and these are not used to power delicate electronic equipments . Here, a simple voltage driven inverter circuit using transistors as switching devices.

Step 1: Components Required

Transformer (6v:220v) - 1 [ Banggood ]

AA Battery Case - 1 [ Banggood ]

Switch - 1 [ Banggood ]

Perforated PCB - 1 [ Banggood ]

BC 547 transistor - 1 [ Banggood ]

BD140 Transistor with heat sink - 1 [ Banggood ]

0.1uF capacitor - 1 [ Banggood ]

30K Ohm resistor - 1 [ Banggood ]

Tools

Soldering Iron [ Banggood]

Step 2: Watch Video First !

This video gives you all the information you need to build your own 1.5v DC to 220v AC inverter. During the next steps however I will present you some additional information to make the project even simpler.

Step 3: Circuiting

Here you can find the circuit.

You can see my PCB traces and it is easy to understand while making.

Place all the components on the PCB according to schematic.

Solder all the components carefully.

After circuiting now the time to test with a 220v bulb.

Step 4: You Made It!

That's all guys you made it.

Feel free to comment.

I only get 3v dc not ac from the output of the circuit, not the transformer.theres no square wave. I am using 2aa batteries.

Post comment...I made this but through 1.5v it gives only 30v...why not 220..through 3.6v it gives 50v..

im working with scrap parts from a junk radio, cant seem to find a 30k resistor, highest i could find was around 22k, will that work?

I wouldn't have thought the exact value of the resistor is crucial so try 22K it might work.

how could I generate higher frequencies? specifically, I want the high voltage, but I want to use something to automatically sweep between 300hz - 800hz (I would Likely use a micro-controller if possible), with a goal of reaching 250volts. Would you know if this is possible?

or better question, what is causing the 50hz - 60hz frequency of the stepped up 220 volts?

Hii!! you can reduce the capacitance to get high frequency and increase the capacitance to get lower frequency.......
