Re: Transformer ringing on cutoff

dpcoyle	Re: Transformer ringing on cutoff Thanks for the explanation, RG. Can you tell more? Do you know, can you you explain, the mechanism of how a perfect transformer doesn't have a problem with stopping current flow instantly? Also, why doesn't the whole winding, not just the leakage inductance, oppose a change in current flow at cut off? The leakage inductance is lost energy and so "just" a series inductor, not a part of the transformed energy. But the energy coupled through the transformer is damped by the resistance, inductance and motion of the speaker; doesn't the work consummed by the load also act to oppose the flow of current? Thanks again, Dan
