Introduction: 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
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
This circuit is divided in three ways.
- Oscillator
- Amplifier
- Transformer
Step 3: 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

Question 6 months ago
Designate transformer, part number, etc
6 months ago
i only want low V AC to play with. so I can, for instance, test rectifying circuits i build. the 240v AC that comes out the wall gives me the willies and i wish to avoid it.
for the transformer could i not just wind it myself with magnet wire and a toroid I have loads of kicking about from gadgets I've dismantled? ideally I want the AC voltage to be the same as the DC input from my bench PSU, so i can simply get up to 30v by adjusting my power supply.
cheers
Question 11 months ago
How would one convert to 110v instead of 220v? Is it as simple as using a 12v to 110v step up transformer instead, or is it more complicated than that?
Answer 9 months ago
By using a center tap transformer, make sure the CT is on the secondary winding, and boom. From CT to H1 is 120 VAC and from CT to H2 is 120 VAC and across H1 and H2 is 240 vac!

Can you show me and explain with pictures,requirements and diagram of a SIMPLE Way of how I can make or invert 12vdc to 240vac output 1500watts to power a washing machine, power jag, rice cooker or TV etc.

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.

no it woun't work.
i tested.
charles is totaly right there: transistors collector must be connected to MOS gate

should work with exact the same parts with 24V
Question 3 years ago
Can i replace irf640 with irf520?
Answer 2 years ago
you mean IRF630, not IRF640 (as used above)?
just compare the datasheets and you will see: the IRF520 is way 'weaker' but should still work.

i can't find anywhere straight one to one ratio (voltages) dc to ac conversion assistance.... can i just exclude the transformer from this circuit of yours to achieve that .... basically what i need is 11VAC 100mA.... i'm thinking of using a 12vdc output (charger/powersupply of many gadgets), push it through something (inverter or like your circuit [minus transformer]) to supply 11vac 100mA for driving a turntable.... obviously some component values will need to be different - could you please assist?

leaving out the transformer will not work.
you will have 1x +12V and 2x GND (or 0V) which will be switched between the both contacts.
When you short the contacts, you will just get a straight forward +12V ...
So what you need is a 1:1 transformer with at least a middle pin on primary.
But you can also use non-1:1-transformers. you will just need to adapt the DC power to what you need. remember: you can't go lower than 4V, or the circuit will not oscillate!

I am emailing from Zambia and my biggest problem and interested is to learn making 12v dc to 220v ac power inverters. Show me where to buy this project components and how much especially for assembling complete power inverters.

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.
