Yesterday, I was testing TL494 circuit, toroid windings & single cell, just to get better understanding on back emf and resonance. First pulse the toroid windings and back emf created from coil directed to cell.
I did notice similar effect like Bedini Monopole circuit. I set the pulse width about 10% and just playing with frequency. While adjusting the frequency, I monitor power draw from battery source to circuit. While adjusting the frequency higher and higher, input power to circuit goes down until at one stage the input draw goes up again.
If pulse width changed frequency need to adjust lower or higher to get the lowest draw from battery source to circuit. Some good information .

Thank you for posting the complete schematic of 3 frequency generator using TL594. I compare with my which works ok. The difference between your and mine was mainly after toroid to cell.
