Re: frequency vs core saturation

Original poster: syd <tesla@xxxxxxxxxxxxxxx>

Hi Scott,
Tesla coils are an air cored transformer. Air cores never saturate so any frequency is fair game. Overall size and geometry of the coil determine inductance, which secondarily will determine a window for the rest of the parameters.
Higher voltage on the primary is beneficial to a point since the amount of energy that the capacitors can hold per cycle is related to the square of the voltage. 2cv2. Higher charging voltage also increases the transformer output impedance, which increases the RC time constant, which means you need more power or a slower break rate to fully charge the caps. Certainly it is all a balance.

Hey all,
    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? I (as of right now) have no means with which to experiment with frequency and input voltage, but mabey somebody else out there does. Thanks a heap. 
Scott Bogard.
