Free Energy from Inverter with Amazing Overunity

Last Updated on August 3, 2020 by Swagatam

free energy

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 […]

3 Best Transformerless Inverter Circuits

Last Updated on January 19, 2025 by Swagatam 270 Comments

3000 watts

As the name suggests, an inverter circuit that converts a DC input into AC without depending on an inductor or a transformer is called a transformerless inverter. Since an inductor based transformer is not employed, the input DC is normally equal to the peak value of the AC generated at the output of the inverter. […]
