DC to AC Inverter Circuit.

By IKTech May 31, 2017

We are all familiar with the approximate inverter circuits. The electronic circuits convert DC power into AC power, which is called inverter circuits.

It can be different quality, different power. We will discuss the circuit of 12 volts DC to 220 volts AC inverter here. It will output 35 watt power. We will add more muscle to the circuits to get more power output.
Required components:

12V battery – 1
MessFire IRF 630 – 2
2N2222 transistor – 2
2.2uf capacitor – 2
680 ohms – 2
12K – 2
12 Volt to 220 Volt Center Tape StepUp Transformer

Circuit Properties

Inverters that are implemented in the circuits are basically square wave inverters. It’s not Pure Sine Wave AC.
It can be operating roughly 35 watts of power.


We can divide the circuit into three blocks –


50 Hz refers to the oscillator, which will supply AC 50 Hz Frequency.

We can get it by putting a stubby multivibre on the circuit. Which will supply us 50 Hz Square Wave AC.

We get the recognition of the R1, R2, R3, R4, C1, C2, T2 and T3 of this circuit.

Here each transistor provides inverting square waves. And the frequency depends on the quality of R1, R2 and C1.

The frequency of the frequency of Frequency produced by the multivibrator that produces square wave analysis.

F = 1 / (1.38 * R2 * C1)

We will amplify the inverted signal from the oscillator using the T1 and T2 of the masses.

We will connect this amplified signal to the primary site of the step-up transformer (center tape 12 volt), according to the diagram. The diameter became …
Some changes made (if you want)

Instead of 12 volt batteries you can use a 24-volt battery. The load will be 85 watts. But this circuit is not well-suited for it. If you want to increase the inverter capacities, you must increase the amount of amounts.

Diameter, you got your fire alarm project. Hope everyone can easily understand.

  • I’m really loving the design of your blog. Do you ever encounter any web browser compatibility situations? Quite a few of the site visitors have complained regarding my house intercom system blog not operating effectively in Explorer but looks amazing in Safari. Have you got any suggestions to assist fix this issue?

  • My spouse and i have been absolutely joyous that Raymond managed to carry out his reports through the ideas he obtained through your web pages. It’s not at all simplistic to simply be freely giving secrets which usually most people could have been making money from. And now we keep in mind we’ve got the blog owner to appreciate for that. Most of the explanations you made, the simple blog navigation, the friendships you can aid to create – it is many awesome, and it’s helping our son in addition to the family reckon that the concept is exciting, which is certainly very important. Many thanks for the whole lot!

  • I wanted to post you this bit of word to help thank you so much as before considering the superb pointers you have featured at this time. This is really particularly open-handed with you giving extensively what exactly a number of people would have made available as an ebook in order to make some money for themselves, and in particular considering that you could have tried it in the event you desired. These solutions also worked to become good way to be aware that other people have the identical zeal similar to my personal own to find out a great deal more with regards to this issue. I am certain there are thousands of more pleasant instances in the future for individuals that read carefully your blog.
