[TCML] Re: IGBT CM600 max current ?

Hi Gary,

The quote mentioned below was *not* from me.  Believe that was Finn's.

To answer your first question:
'So assuming an adequate DC power supply and 50 kHz as the resonant 
frequency of your Tesla coil's secondary (with a slightly larger topload 
attached), then a break rate of 50,000BPS will be no problem as long as 
the RMS current does not exceed the transistor's RMS current rating, 
correct?  G.P.'

That is correct.  But of course the transistors' RMS rating will have 
been exceeded long before the break rate reached 50,000BPS.  Probably 
around 1,000 to 2,000BPS.   GL

available to get any higher.
