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.
