I'm look at an existing design for a high power Class D audio amplifier type circuit. Its not for driving speakers but other than that the circuit is the same.
I am getting failure if the load is higher than a certain value (e.g. less resistance).
At the moment I'm trying to work out the current rating of a custom made toroid that a past engineer has designed. I am having trouble understanding which formula I should use. I thought the general EMF equation - but its got to be rated to current in some way? Also I assume we use the PWM frequency for calculations, not the output frequency?
