Is this Inductive Overunity? Maybe Not

Last Updated on May 20, 2026 by Swagatam

radiant 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 […]
