Re: frequency vs core saturation

    Here is a question for all you mathy theoretical technical guys.
I heard In physics class tonight, that if you use a higher frequency you can use a smaller core for a transformer. In my mind this means, if you use a higher frequency, you can pump more voltage through your primary, and consequently get more out of your secondary. This means (provided you have enough insulation) you could use a much higher voltage in your TC primary, with the same transformer, by changing the input voltage and frequency, without saturating the transformer core. So my question is, is this beneficial in any way? Is this even true, or is my logic flawed?
It's true, but, seems like the physics teacher forgot to mention about increased energy loss in the core material when the frequency is increased. If the material is iron, and a mains voltage & frequency HV transformer, already near 100 Hz it starts smouldering...
