While experimenting with a 300V DC to 220V AC inverter circuit, I noticed a strange overunity phenomenon which appeared to be like the generation of free energy from the inverter transformer.
Recently while experimenting with a high voltage converter circuit, I was quite astonished to see a strange overunity kind of occurrence wherein the inverter transformer output seemed to be generating more power than it was being supplied.
The entire set up can be witnessed in the following diagram:

Connection Diagram
Is this Free Energy from an Inverter
In the above set up we can see a very common center tap inverter topology, wherein the transformer center tap is connected with the positive input from the supply, while the two outer ends are connected with the drains of switching mosfets.
The gates of the mosfets are switched with an SPWM 50 Hz oscillating frequency from a 12V DC oscillator stage. The oscillator stage is powered from a external 12V DC battery.
The battery here, is only associated with the oscillator stage, and has nothing to do with the transformer power stage.
The actual power to the inverter is introduced from the mains 220V socket after appropriately rectifying it through a bridge rectifier network using 1N5408 diodes.
To ensure that in case of an accidental mistake in the connections nothing goes into smokes, I decided to connect a 200 watt incandescent bulb in series with the input mains supply during the initial testing of the circuit. This bulb can be seen as Lamp#1 attached in series with the input 220V supply.
After this, I switched ON the 220V mains power for initializing the inverter operations.
I was happy to see that the inverter started working without any issues. However since there was no load connected with the transformer secondary, I was still not sure about the results and regarding the actual performance of the inverer design.
Therefore to test this I connected another 200 watt bulb having exactly similar specifications to the Lamp#1 with the secondary of the transformer.
Witnessing the Overunity
I switched on the mains once again, and was quite amazed to see that the Lamp#2 connected at the transformer secondary switched ON and illuminated with a relatively higher brightness compared to the Lamp#1, which hardly showed any illumination on it.
Lamp#2 was glowing with around 40 watt illumination while the Lamp#1 was barely glowing at around 5 watt illumination.
Since all the power to the transformer was being delivered through Lamp#1, the power sharing should have been perfectly equal across the two bulbs, meaning the illumination on both the bulbs should have been equal, but here the conditions did not seem to be following this rule.
This seemed baffling to me, and I am still struggling to find the answer regarding how the bulb connected with the inverter could produce 6 to 8 times more illumination than the series bulb which appeared to be supplying much less power to the inverter?
From the situation it seems free energy is being created from the inverter with an overunity of 400 to 800%, something that certainly deserves a deeper investigation.
Without the Inverter Circuit, Power Distribution becomes Equal
The following video proves that normally resistive loads having equal ratings will share and divide equal power across them. The video shows how the two 200 watt bulbs produced identical illumination (100 watt each) without the inverter circuit involved.
Second Video Confirmation
I tried the experiment one more time, just to confirm whether the results were consistent or not, and fortunately the experiment yet again proved the above explained overunity occurrence, leaving no doubts regarding the perceived outcomes. Here's the video for you all to watch.

Now I understood you point.
You are asking that ‘ how it is possible that a transformer and a bulb can consume different watts. while both are connected in series.
it is possible in this type of setup .
I will try to explain with some practical value of watt , volt , amp, duty cycle, frequency, rectified DC , kva , etc.
Good night!
Swagatam Ji,
I think ‘RL circuit in series’ will explain all the doubts about free energy of this circuit.
actually transformer is consuming more power than bulb1 , that is why we are getting more power at bulb 2.
bulb 1 has less volts compared to transformer input but same current.
total consumed power by bulb1, oscillator and transformer will be more than output of bulb2 .

Devendar Ji, Bulb1 is in series with bulb2 circuit, so any power consumed by bulb2 will be reflected in bulb1, because both are of same rating. You cannot pass more power to bulb2 through bulb1 by keeping bulb1 cold.
let’s forget about voltage and current, let’s compare the heat on the filament.
If suppose the heat on filament of bulb2 is 200 degrees C, then the heat on the filament of bulb1 should be also 200 degrees since the power is entering through bulb1…right? How can filament of bulb2 generate more heat than filament of bulb1 since both are technically in series and the actual power is entering through bulb1??
Swagatam Ji!
I hope by now you have got idea , why bulb 2 is glowing more than bulb 1.
I was taking about RL series circut
But you checked RC network .
RL series – when resistive load and inductive load ( coil , inductor , choke transformer) connected in series.
RC – when capacitor connected in series
with R
let me explain in a simple way .
bulb getting power from secondary winding of transformer , secondary winding is getting power from primary winding, and primary winding is in series with bulb 1.
bulb 1 takes less power than primary winding. hence bulb 1 glowing less than bulb 2.
What is rating of transformer you have used in circuit.

Devendar Jakhar
Devendra ji,
What you are saying is not explaining the condition or the question that I have raised.
When two identical bulbs are in series with the supply their glow has to be equal. Here all the current (or power) to bulb#2 is passing through bulb#1. If bulb#2 is glowing at say 40 watt, this 40 watt power has to pass through bulb#1 also right? Therefore bulb#1 should also glow at 40 watt? I
you are saying bulb#1 “takes less power from primary winding” of the transformer, so from where does bulb#2 get the extra power?? If according to your judgement say primary gets 5 watts from the bulb#1, then from where the extra 40 watts arrive at bulb#2??
I hope by now you must have understood the point.
Hi !
this is a RL circuit in series. just Google ‘RL circuit in Ac’ you will find all the answer.

Devendar Jakhar
Hi, yes that may be correct, I went through all the formulas and descriptions but nothing explained how the lamp2 is able to produce more illumination than lamp1? If you know the answer please share with us.
Here many parameters are involved, 100Hz from the bridge, PWM frequency from the circuit, and the transformer’s flyback topology, all these cannot be considered as a simple RC network
and what is that capacitor across the bulb which is glowing brightly.
It is a 105/250V PPC capacitor, but I don’t think that may be relevant to the situation
Hi sir,
Where can I find 220 -0 – 220v to 220V transformer and MOSFET?
Let me try to investigate a bit deeper, this is really interesting and yeah I too don’t believe in free energy.
I will be using two 100w bulbs. And to be on safer side I will use a computer UPS on battery mode for mains input to your setup. On oscillator stage I will use AMV or Arduino SPWM generator with proper current limiter circuit (LM317).
Will this emulate the same setup of yours ???
I will measure AC current consumption vs output AC current.
I am ready to face the disappointment in the experiment, as nothing called free energy. but let us investigate what is the reason behind this phenomena / illusion.
Regards
Hi GR,
I just checked the transformer secondary specs, it is actually 110V, however I am not considering the voltage or current here, I am only considering the illumination level. Lamp1 and Lamp2 both being 200 watt with their ratings should have shared same illumination under any circumstances, since both are apparently in series with the power line.
Filament bulbs can never create an illusion, because the glow on their filament will be directly proportional to the consumed power, therefore if Lamp1 is glowing at 5 watt then it must be consuming 5watts and lamp2 should be consuming around 40 watts, so where is this extra power coming from? That’s the question.
If it is working with a 220V-0-220V to 110V transformer, it should work with any other smaller version also.
You can try this with a 12-0-12V/220V transformer. Feed the 12V DC from another transformer rated at 12V/220V by rectifying its output through a 1N5408 bridge, don’t add any filter capacitor to the rectified output.
add a 100watt or 40 watt bulb in series with the primary of this transformer, and connect another 40 watt bulb at the output of the inverter transformer…this should replicate the above concept perfectly.
You can use Arduino SPWM for this experiment for the initial test.
Hi Swag,
I read your post and I am it is due to emf produced in transformer. I have seen it when I was working on invter with little higher frequency than 50hz. try to use something else instead of lamps or increase the distance. You know I am also working on same thing to find out if it is possible to consume this power generated in air by magnetic fields. to proof, try to connect your multimeter negative prob to ground and bring positive prob near to the system, you should see some readings in meter. same multimeter experiment can be done while you charge your battery. put positive prob near to battery and negative connect to ground.
Hi Saqib, yes that should be happening because of a back EMF but anyway it is generating more output than the input? That’s the question which needs to be investigated.
hello good job you can put the component list please thank
thank you, the mosfets are APT29F100B2 and the inverter can be any suitable SG3525 based circuit…
Namaskar !
Your blog is awesome!
Great job you are doing!
You was not agree with free energy concepts , written by other writer / researchers in your blog.
there are millions of fake videos on YouTube about free energy.
This time article was written by reliable trust worthy and very knowledgeable person Mr. Swagatam , so I was very exited .
I did some experiment with my inverter based welding machine . but result was not as expected.
transformer is different type in my machine.
input to the tranfomer is not 50 hz but may be some kHz .
If you found still now your free energy system working properly please let us know.
if you found it was because of faulty components in your circuit or faulty connection or circuit .
please update .
I m waiting your update .
Thank you very much
Hi, thanks for liking my website. appreciate your interest!
The above mentioned phenomenon was accidentally discovered by me while testing the aforesaid inverter design.
I still don’t believe in free energy systems which are discussed on various websites and youtube channels, unless there is some scientific truth behind the concept.
I have explained above what I actually saw during the experiment. If possible I’ll try to conduct the experiment once again soon, and reconfirm the results with a video shoot.
Swagatam Ji,
Please update status .
If you have tested and verified result again, with fresh experiment .
Thanks
I have the updated the video.
Thank you , Swagatam Ji. I saw your video , it’s amazing! I want to build this one. Please suggest me oscillator circuit. Transformer you have used seems different type. Can I use different MOSFET . Regards Devendar Jakhar
You are welcome Devendra ji,
I used the circuit from the following article:
https://www.homemade-circuits.com/1500-watt-pwm-sinewave-inverter-circuit/
the transformer had the following specs:
primary 220-0-220V, secondary (output): 110V
Mosfets: IRFPG50
You can use other mosfet depending on the input DC voltage and and load
Devendra ji, I’ll try to repeat the experiment this week, and update the video here.
OK.
Good luck
