1.5v DC to 220v AC Converter

DC to AC Power Converter are often needed at the places where it is not possible to get AC supply. DC to AC power converter circuit is used to convert the DC power to AC power. In this article we are going to make 1.5v DC to 220v AC. Converters can be of two types pure sine wave converters and quasi or modified converters. Pure sine wave converters are costly but  modified or quasi converters are inexpensive.These modified dc to ac power Converter produce a square wave and these are not used to power delicate electronic equipment’s.  I am explaining a modified DC to AC converter in very simple way with only 1 transistor and Two transistors.

power converter with single transistor

In first circuit diagram we have built a very very simple dc to ac converter with single transistor only. Its not Pure sine wave inveter so please do not check its output with multi meter because your multi meter will be damaged if you check the output with it.

12v to 220v Ac inverter

Components required

  1. 12v Battery
  2. 2sc5200 Transistors
  3. 220ohm to 1k Resistor (depending on your transformer)
  4. 12-0-12   220 Volts  step up transformer. (6-0-6 transformer will also work)

A 12 Volts DC to to AC converter can also be designed using MOS FITS.


Principle Of this Circuit

The basic idea behind every dc to ac converter circuit is to produce oscillations using the given DC and apply these oscillations across the primary of the transformer by amplifying the current. This primary voltage is then stepped up to a higher voltage depending upon the number of turns in primary and secondary coils. keep in mind if the turns of coils will be more then converter will produces high volts and if the numbers of turns will be few then it will generates low voltages.

Components required

  1. 12v Battery
  2. 2sc5200 Transistors
  3. 1 to 5k Resistor (depending on your transformer)
  4. 12-0-12   220 Volts  step up transformer.

You can also design DC to  AC converter with mosfit.

Two Transistors Inverter

Its also same like single dc to ac converter transistor invert-er only difference is that it has two transistor 12v inverter. Its power is two time better than single transistor dc to ac power inverter .

The transistors which we have used are also very powerful so these transistors can not heat up while working.

working is same like single transistor you may use 6-0-6 transformer with 6 volt DC. Its an experimental invert-er. you can use PNP transistor instead of NPN only ischemic will be change here we are also uploading the circuit diagram with PNP transistor.

  1. I hаve been browsing online more than 3 hours today,
    yet I never found any interesting article like yours.
    It is pretty worth enough fоr me. In my vieѡ, if all site owners
    and bloggers made good cоntent as you did, the web will be
    much more useful than ever Ьefore.

    1. thanx a lot for my encouragement in a encouraging mode. Dear your encouragement is my power please always keep me encourage
      i will be great full to you thanx

  2. Hola mi nombre es Bernardo y tengo una pregunta, este transistor 2sc5200 NPN puede ser reemplazado por el 2N3055? para poder hacer este inversor de CC a AC con el transformador de 12 volts a 220 volts AC y con las 2 resistencias de un 1k espero su amable respuesta gracias mi correo es : bernardo102_1@hotmail.com 🙂

    1. sí, por supuesto, ambos transistores son muy potentes, puede usar 2c5200 / 3055
      estos transistores tienen mucha potencia y pueden usarse

      muchas gracias por visitar mi sitio web y perdón por la respuesta tardía

  3. How much power we can withdraw, aka current output we can get with Single transistor and double transistor? Secondly how is voltage regulated or output voltage? Third what is the frequency of SINE wave we get ?

    Happy to see your post and it is informative. I am working on DIY on making simple inverter board to run a induction based fan and tube light. I will wait for your reply.

  4. Great writeup. I checked out your blog site pretty often, and you’re always coming up with some decent

  7. Hola aqui estoy de vuelta Bernardo Lopez D… y tengo otra pregunta estoy experimentando con unos FLybacks pasa a lo siguiente: lo que pasa es que le conecto un transistor 2N3055 y le agrego unas resistencias de diferente capacidad, por ejemplo (5w 22 ohms) y (5w 220 ohms) tambien le he agregado otras resistencias de otra capacidad que son (2w 22 ohms) y (5w 220 ohms) aparte le he agregado otra que es (2w 22 ohms) y la otra es ( 5w 560 ohms) el par están soldadas en serie primero pongo un par luego las quito luego pongo el siguiente par las que siguen pero hay un problema el transistor 2N3055 después de unos 30 Segundos deja de funcionar me avienta una chispa de unos 2 cm con 12 volts 1 amper si le duplico la carga o sea a 24 volts funciona unos 15 segundos o 20 a lo sumo y después deja de funcionar y con los 24 volts me avienta una chispa de unos 3 cm aproximadamente aunque el transistor 2N3055 se caliente poco que estará pasando? yo se que el transistor 2N3055 es muy potente pero no dura casi nada sera problema del FlyBack? espero su amable respuesta mi correo es bernardo102_1@hotmail.com Gracias y que Dios los Bendiga 🙂

  8. Bonjour !
    Je suis vraiment satisfait de voir cette page, qu’est-ce-que je peux utiliser comme composant si je veux fabriqué un convertisseur 12V à 220V 5 KVA?

    Merci pour votre soutien.
