Introduction: Simple Dc to Ac Inverter Make

Picture of Simple Dc to Ac Inverter Make

It's very easy to made DC to AC inverter circuit. This inverter circuit convert DC power to AC power. It can be different value and different power.

I will show you convert 12v DC to 220v ac. It will give output about 35 watt. We can get more output to add more MOSFET.

Step 1: Required Equipment

Picture of Required Equipment

Require Component:

  • 12V Battery- 1 piece
  • MOSFET IRF 630 - 2 piece
  • 2N2222 Transistor - 2 piece
  • 2.2uf capacitor - 2 piece
  • Resistor- 680 ohms 2 piece and 12K 2 piece.
  • 12V to 220 Volt center tap transformer.

In this circuit, the inverter output will be square wave. It's not a pure sine wave. It can operate 35 watt power load easily.

Step 2: Main Three Part of the Circuit

Picture of Main Three Part of the Circuit

This circuit is divided in three ways.

  • Oscillator
  • Amplifier
  • Transformer

Step 3: Working Procedure

Picture of Working Procedure

Working procedure:

50Hz oscillator means 50Hz frequency ac supply. In this circuit, we will get oscillation by R1, R2, R3, R4, C1, C2, T2, and T3.

Every transistor will provide inverting square wave. The value of frequency depend on Resistor 1, R2, and capacitor C1. We will amplify MOSFET T1 and T2 by oscillator power.

Now time to connect the equipment according to circuit diagram. I hope you can do it easily by yourself. It's very easy to do. If you have any question then ask me. You can get more info from here: voltage lab

I'm a bit confused. The schematic shows 2N2222s and IRF630's. The picture shows two TIP31's and no FETs or 2N2222s.

Although not shown in the diagram, the wires running between the collectors of the 2N2222s and the 680 Ohm resistors must be connected to the wires that run between the FET gate and the 2.2uF capacitors.

Finally, some transformers may have characteristics that cause the voltage spikes at the Drains of the FETs to go higher than the 200V limit of the IRF630 (especially with a minimal or no load). A couple of 150V TransZorbs connected between each Drain and GND would help protect the circuit.

It's quite different from step picture. If you draw the circuit according to circuit diagram then it will work good. It runs perfectly.

If you were to connect a motor instead of the DC battery and turn the motor would you essentially have an AC generator?

In theory, yes.
