- Hello all :)
This video is a continuation of my previous video of making a DIY inverter of 200 Watts capability. In this part I have converted the high voltage 220V DC signal into a square wave signal of 220V of frequency 50 Hz. The project uses very simple components and I got some of them from old unused electronics. This is a quite efficient inverter that can easily be used to power medium scale appliances like a small table fan,laptop and mobile chargers and CFL bulbs without a problem. It also has low battery cut off feature and all of this is without using any microcontroller.
This is not a sine wave inverter so not every AC device will be compatible with this design.

Very good work, well done
Excelente amigo , busque por internet algún ejemplo practico con detalles de mediciones y bien explicado , muy bien video , animo mas videos , saludos .
Friend a question this circuit that you made to transform high frequency current and lower it to a current of 60hz Sele can put any inverter I have one with a ferrit transformer
Very neat and crystal clear explanation and experiment...👏👏👏👌👌
Thanks a lot!
Great thinking
Tks, friend!
Great video just loves the way you explained each step of the assembly. What modification would be required to make it work for higher AC output such as 230v21a and 230v42a? Kindly suggest the modifications. Is it ok to email you?
I'm a holiest of eclectics, your videos are very helpful and well explained. I have questions
1. Does high DC voltage effects inverter durability(is it possible if get 110AC Voltage and then we step that AC voltages) ?
2. Does the IC and mosfate driver (that you have used in this project) need specific code modifications or they rebuild functionality?
High voltage DC would not effect the durability if the components you have used are capable of handling high voltages. The switching ICs that I have used work from 9V to 12V and you must find a way to convert the high voltage DC to lower levels so that you can also power those ICs with it.
The MOSFET driver I used here can be used to connect to MOSFETs that can switch 700v but the operating voltage of the IC itself it low
Amazing video..
Thanks bro :)
is this a standalone circuit or must be linked to the inverter part 1? if so how to cascade them?
You can also use it as standalone. You can connect it to the high voltage generator of part 1 also..I have mentioned the connection in the video description link
Hi bro great project, I have EE42 transformer any idea how much power it can handle ?? I also want to make same inverter as your but just a little bit higher power like about 500W.
Yes with the EE42 you can go upto 500W. Just add more switching MOSFETs in parallel to increase the current handling capacity.
@@UtsavShah_25 thank you 😀❤️
I buy 60 pieces of ir2014 and connected the driver exactly but I get no low signal it’s dead all 60 get no low signal SD connected to 14 volt no signal only the boostrap work I don’t get it
Hi, you explained great. We would beg you to mark on the mosfet where G D S
Thank you for your feedback! The first pin starting from left is the GATE pin followed by the DRAIN and SOURCE pins. For better understanding, datasheet is the best resource
good verynice (feed back protection mising)
Design and upload 500w with snubbed and series coil protection ckt, min 500w is required for average apllications
Pls reply my below some questions?
1. Can we connect directly with 220v DC coming from a solar bank?
2.Then how can we give power to SG3525 with 12 volt.? Can we attached a 12v smps module with input of 220dc to 12v dc for powering the ossilator?
3. Can we add some feedback circuit for steady 220vac output?
4. How to get sinewave 220v ac from it. Is it possible to get sinewave with attaching a non-polarity cap such as 1uf 400v.
1. Yes you can connect 200V DC coming from solar panel to H bridge. But the voltage may not be stable due to solar voltage fluctuations.
2. You can use any 220 to 12V smps based adapter to power the SG3525
3. In my circuit I have a provision for feedback in DC to DC conversion section.
If you want a feedback in stabilization of 220V of solar then you may need to purchase a solar controller or a buck boost converter capable of handling that voltage levels.
4. You can use a H bridge circuit and EGS002 module to convert this DC in sine wave AC
@@UtsavShah_25 A BIG thank you.
बेहतरीन निःशब्द
Thanks!
nice job but what is your output voltage ?
Output voltage is a 240 volt square wave AC
This is project has overcurrent / Overload protection? What will hapen if i use high load?
No, currently this circuit does not have an overcurrent protection and it may get damaged if very high load is used
For 50hz source can I use aurdino ?
Yes you can use arduino to generate 50Hz.
where is test with 200w incandescent light bulb? Since you wrote in a description that it's 200w converter? Or it will burn out with 200w load?
It does get a little hot handling 200 watts but can be safely used. I haven't tried it with an incandescent bulb. Thanks for letting me know. Will try to include this test in any of the related future projects
Hi sir What is the value of your bootstrap capacitor on gate driver?
47uF/25volts
Good circuit!!!
i want to same 400 wattages or 500 wattages circuit
Will try to make one in a future project
Hi!
I have made the circuit but when i put load of 180w the voltage drops from 220v to 170v can you tell why? The transformer iam using is extracted from 500w car inverter which is already winded for this purpose. I want the voltage to be stable to 220v or any other voltage which i have set. I have also set the voltage to 320v by potentiometer but on load it drops to 170v.Please answer iam waiting for you reply.
Check if your switching MOSFETS are getting too hot while working under the load, in that case replace those with more powerful alternatives. You can also try and adjust the feedback potentiometer while the circuit is under load to better tune the voltage regulation. Also check if your input DV voltage drops if you apply load, in that case use a more stable DC supply
@@UtsavShah_25 mosfet are mounted on heat sink so they are not getting hot. I have tried to adjust the output voltage under load using potentiometer but there is no difference it works only on no load.
@@UtsavShah_25 iam using 12v battery it voltage drops but not that much like it is at 12.5v at no load and comes on 12 volts on 100w load. The purpose of sg3525 is to compensate for output voltage drop whether the voltage drops from battery or not like in this case it drops to 12v. In 12v dc to 220v ac converter this thing does not happen whether we put load on battery or not the voltage keeps on 220v. I want this ic to work like that. It is the same ic which is used in commercial UPS systems.
@@UtsavShah_25 thanks for your reply
You need a feedback from the output to the non inverting input of the ic to compensate the output voltage.
you may check this out. he described the ic very well.
th-cam.com/video/BmaXe0dME5M/w-d-xo.html
Weldone for a good Job sir.
please can u give pcb file . That will enable printing on pcb board
Hi thanks for the feedback. You can check out my instructable page, the link is given in the description of the video. I have the schematic file there
Best can you maker 450v dc or 500v Dc?
Yes you can also get that by increasing the secondary windings and increasing the voltage rating of capacitors
Can i increase 1000 w that?
@@dacreation369 for 1000 watt you will require 2 transformers and more switching MOSFETs
Best.can you make a re design that cerkit.because it is good 1000w pio sine wewe innveter s. We can canect derelict home .decause Ac instument ran Dc curant .what is think about that .I like your best video thank you
what will be the output if a spwm signal is fed to ir 2104 driver ic ?
You have to give complimentary SPWM signals to the two MOSFET drivers and you can gen get spwm AC square wave signal at output
@@UtsavShah_25 so can u please make a 50 hz sinewave inverter .is it possible to get sinewave output by adding LC filters..
Yes I am working on it, will post the videos soon
Pls if we can use ir2110 can you design one.
Yes it can also be done with IR2110
Pls can i parralel the mosfet upto one thousand watts output put ????
You can but you will need a transformer capable of 100watts as well
Can I use ir2110 driver ic replace with ir2104
Yes you can also use the IR 2110 for this
What is the use of h bridge driver?
It converts the DC to AC
I am trying to make one PCB for both parts. When I finish it I can share it with everyone
Seems like a good project all together!
Did u complete the projects?
Pin 3 and pin 4 are not connected.. is it ok for proper operation
Yes you can leave it unconnected or connect it to ground
@@UtsavShah_25 thank you sir..👍👍
Can we use ir2110 ic as driver
Yes that can be used as well
@@UtsavShah_25 Thank you
Whats is volt the elco 47uf???
25 volts
Thanks lot
No secret
Open mind
Good video
But I didn't try
I have to do
Thanks a lot for sharing your feedback!
Hellow bro which component use in it
Hi, you can check out the instructable link in the description for component and schematic
Thank you brother lam subscribe your channel
@@chudasamakiran9747 thanks a lot!
Ise high power ka banao bhai
Beter to increase deadtime by increasing R2 to 470R
I want this
Plz...
Mai kaise kharid skta hu
I am not selling this as commercial product
@@UtsavShah_25
Ok
Mere pass solar panel set h jiska output voltage 200 DC
Kya e circuit work krega
Why AC voltage is not stable
Voltage is stable. It has feedback to ensure the set voltage remains constant
Where to connect 2 x 330mf/200V, in diagram.
Both capacitors are in series connected across the high voltage output of the DC DC converter
Can we EGS-002 instead of SG2535 to generate a Pure sinewave output?
Yes you can surely do that
how to convert 72v dc battery to 220v ac to use at home
You can reduce the number of secondary winding of the transformer to make it compatible for working with 72volts. Also make sure the switching MOSFETS at the primary side can handle 72 Volts
IR2104 mosfet driver ic jajuri tha. Local market me nahi mil raha hai. Kya aap de sakte hai
FAN7382 ya fir IR2110 use kar sakte hai, pin configuration alag hai but use kar sakte hai
Ye ic mil nahi raha hai
Could send the full diagram of your inverter
You can check the first part of the video where the high voltage generation is explained. Combine this with this H bridge circuit and you get the complete circuit.
I have made this project into two parts
Diagram please
You can check out my Instructables page for the schematic. Link is in the description.
Well that is interesting..
Your certainly get from me a BIG THUMBS UP!!!..
But what i would like to know is how to improve the wattage output to 5000watts,since i've built myself a generator that has an output of 240V DC.
PLEASE spare me the idiotic comments its not possible! coz here everybody should know any electric motor DC or AC can generate electricity one way or the other with few twicks here and there!!! .....well if you didn't know any electric motor can generate electricity well rather than go back to school "coz you waste only public money" alot of practice which means trial and fail trial and get it right!!!...
USE YOUR BRAIN:what basic materials are used to make an AC generator?
well round sheets of metal with a hole in the middle for the rotor small steps to slide in the copper windings,copper wire,magnets.
USE YOUR BRAIN:what basic material are used to make an induction motor?
well round sheets of metal with a hole in the middle for the rotor,small steps to slide in the copper windings,rotor small enough round sheets of metal and aluminium to keep the round sheets of meta tight together...
HOW TO MAKE AND INDUCTION MOTOR WORK AS GENERATOR???
well you have 3 possibilities;
1 magnetize the rotor.
2 drill holes in order to place on it magnets.
3 put in one coil 220 AC,make spin the rotor and pull out from the other coil 220V AC.
since that inverter push out 200 watts well it should be enough to magnetize the rotor and make AC come out the other coil."MOST IMPORTANT YOU HAVE TO REMEMBER YOU DON'T NEED TO USE THE INDUCTION MOTOR AS SUCH BUT AS GENERATOR WHICH MEAN YOU HAVE TO DRIVE THE INDUCTION MOTOR ROTOR WITH ANOTHER MOTOR EVEN A DC 12 MOTOR FOR BICYCLE WILL BE ENOUGH TO MAKE GENERATE ELECTRICITY,MOST DEPENDS ON THE RPM OF THE INDUCTION MOTOR AND DC MOTOR".
As i said above trial and fail trial and get it right,at school teach you only theory,making things with your hands make you learn if on thing work or it doesn't..
Hello! As I understand you are looking to generate more power using the concept of a generator which is mot this circuit is intended for actually. In case of generators you need a bigger dynamo and a powerful force to drive the dynamo
@@UtsavShah_25 Hi!! sorry but you got it wrong.
What i am asking is how to increase the watts output of your board to 5Kw.
I already have a generator which has DC output of 240V DC and i need to convert the 240V DC into 240V AC.
As far as i know there is no dynamo that generate 240V DC,the highest dynamo output i know of has 48V dc output commercially available,nor someone has built one.
@@scamper_van8470 Okay now I got it. You can increase the power output by using the H bridge MOSFETS in parallel so as to increase the current rating.Another way is to select MOSFETS that have already a high voltage and current rating ( 600V and 30amp capable)- you would still need to use them in parallel to increase current handling capabilities
@@UtsavShah_25 Hi and thank you for the answer.
So if i get it right all i have to do is increase the number of MOSFET's to reach 5000watts,or pick MOSFE's 600V 30Ah?
If so how do i calculate how many MOSFET's i need to reach 5Kw?
Now that i am checking ebay i may have got the answer,if my guess is right 600v 30A 10x500w=5Kw to be on the safe side lets say 11 MOSFET's?
Requirment input 250V DC output 220V AC
