nickk hello, I need for your help.
please help, I need a 12 DC to 220 AC inverter 1000 watt, modified sine signal at least.
can help me to complete the circuit and details of the components used.
The full series of images please send an email to me: or
thank you before nickk ..

sir I am trying to make the not able to generate the sine wave can you please reply

amer.ozeir (author)Nick_Zouein2015-01-12

hello can u tell me plz why u are using two types of transistors in your H-bridge what's the point behind this

kathkathmina (author)2015-02-08

HI can I use 2N3773 transistor instead of 2N3055?

fahed jaber (author)2014-11-09

it's very gooooooooooood

firdaus.mohamad2 (author)2014-11-08

anyone can help me..i need solar battery charging circuit and inverter circuit produce can share circuit in my email

Aldrin Dalagan (author)2014-11-04

Hi Sir NICK.. Can i change the transformer into 24-0-24 center tapped to gain more power? I am using 24-0-24 but unfortunately.. it burns all of my 2N3055 transistors

hi cool work but how much amp i need for the 1500w

hi nick
for IC CD 4047 special or not thanks

g4nori (author)2013-06-05

hi, can i use a "4093" IC to generate the clock?

ssundhar (author)2013-04-01

hi mr.nick zouein am sundhar from india. ur circuit deatails are very awesome.then i want need to quick charging for ur please sent the details 4 quick charging circuit

suhendro_86 (author)2013-01-16

hello nick,
whether the scheme for 12DC to 220ac inverter with a power output of 1000W (min. MSW)?
Can you let me know? I want to assemble for my home needs.
thank you ..

dadung (author)2012-07-29

hello nick, whether the scheme that uses mosfet inverter irfp 260 n
2000W.i want to assemble. Thank you

Nick_Zouein (author)2012-06-15

You can yes but you will not take out of it a full 500w and it will not last more than 30 min. I don't suggest you do so, this is not professional work.

Hi nick What is the value of D1

general purpose 6A diode

Wild Hunter (author)2012-05-10

Hello Nickk,

What would be the voltage rating of both the polar capacitors?
And would this voltage rating of both the capacitors remain same as we increase the output power rating?

Wild Hunter (author)Wild Hunter2012-05-10

Please also tell me that about the
1- Vcc selection for higher watts is same as was in your previous design?
2- The transformer center tape winding selection for higher power is same as
it was in your previous design?
3- Is the selection of Amp for transformer for higher power is same as your
previous design?

Can anybody help me please, I cannot read the comoponent specs on the jpg pictures. Numbers are very small, How do you do ? I am missing something ?

Thanks in advance for your help.

Best regards,

HARRIS747 (author)Nick_Zouein2012-01-31

Thanks very much Nickk !

Now I will start asap !

Kind regards,

valeso (author)2010-07-09

helo nickk thanks for your precition about the kind of battery to use but i still have another pre-ocupation can the current produce by the inverter be use to charge the battery?that is like a closed cycle.

Nick_Zouein (author)valeso2010-07-11

No it doesn't work, there is power loss in the form of heat generated by the power transistors that will eventualy empty your battery

Basem Salep (author)Nick_Zouein2011-12-28

hi nickk i'm in Don Bosco school in Egypt our project this year is to make an inverter version 250 watt we use it to transform from 12 Dc(come from 2 solar panells) to charge a bettary to make it have i to use 6 transistors pnp?

aashay007 (author)2011-12-10

can i use this for el wire ? or can you give me source to another one for that purpose ?

za-experimenter (author)2011-11-23

Thanx for the awesome instructable!
Am really looking forward to builing my own inverter!!

analyndalin (author)2010-08-25

nick thank you very much for this very good circuit, we build it and perfectly working this very helpful to us to pass our subject... god bless...

vinnu369 (author)analyndalin2011-02-03

gud eveng
i am vinil
i am doing my BE in electronics
can u send me an 100w inverter circuit which u got perfect output

here is my mail id

Nick_Zouein (author)vinnu3692011-11-22

it is already online, can't you see it ?

karthim09 (author)vinnu3692011-07-06

hi vinnu,

i saw the circuit of 12vDC to 220vAC 100watts inverter in instructable. if you hold the circuit for that one.if possible please send me.

my mail id is

Nick_Zouein (author)analyndalin2011-11-22


divinewrath00 (author)2011-11-11

sir can i use 9vDC supply and not 12vDC and still have the same output of 220vAC/100W?

you have to change the transformer to 18/220 v center tapped

todo123 (author)2011-10-21

hey nickk, can you give me the names and parts? so i can order them fast and easily. (author)2011-07-15

is the jumper is necessary? can i use mosfet in the power stage instead of transistor?

analyndalin (author)2010-08-22

i mean, i used the t1 for charger circuit separated circuit from inverter. it is possible? thank you.

analyndalin (author)2010-08-21

hi nick, i would like to add a charger in this circuit, can i also use the T1 transformer for the charger? thank you.^ ^

Nick_Zouein (author)analyndalin2010-08-22

no, to charge a 12v battery you'll need 13.5v not 12v

analyndalin (author)2010-08-21

hi nick, what is the value of R1 for 60Hz the value of D1 and the voltage value of capacitors? please reply asap coz i built this inverter for my school project but i don't know what are the components value that i mentioned. thank you very very much.

Nick_Zouein (author)analyndalin2010-08-22

for 60Hz : replace R1 with 39K and C3 with 0.1uF metalized film 5% tolerence, use 25v caps for C1 and C2

yeng (author)2010-07-20

sir; CD4047 is not available in my place,. is there any substitution for this? many thanks..!

yeng (author)2010-07-11

Hi sir: If I would make up to 3000 watts with this circuit, do I need to change the transformer and the input voltage like what you did in your PWM version? And is it ok f I use 39K carbon resistor for R1 instead of 250K variable resistor?..can i use 2n3773 as replacement of 2n3055?..tnx..!!

Nick_Zouein (author)yeng2010-07-11

hello, yes go by the table of the PWM for best results and efficiency. i don't know if 39k will give you 50Hz, try it. Yes use 2n3773. Regards

valeso (author)2010-07-09

then about the 2ns and the tip is the current of the battery not going to burn it since the 2n3055 seen from my datasheet can support 15 amp?thanks.
