Abstract
A method and apparatus for testing flyback transformers counts the number of cycles of a decaying ringing signal generated in a resonant circuit including the secondary winding of the flyback transformer beginning with the second cycle and ending with the cycle where the amplitude of the ringing signal falls below twenty-five percent of the amplitude of the second cycle of the ringing signal.
