RE: [TCML] Primary/Sec. Frequency



Tim,
A secondary giving 82khz implies an 8 or 10 inch diameter, but a primary
that is wound to fit around a secondary that size, would I imagine have a
lower freq than 164 kHz, unless of course you're using very few turns.
Check the dimensions that you entered and what JavaTC gives you, and post
the JavaTC output file (use the "Format Design as text" button, then select
and copy, and paste into your email.)

Thanks Phil,

The numbers from my first try on Java didn't look right. The calculated 
primary resonant frequency was 82.81 KHz and the secondary was 164.75 KHz. 
The HV power supply will be a 14,400v PT.

I'm not sure how I got so far off, but will modify some of the main 
parameters. Any suggestions will be appreciated.

Keep in mind you will be trying to explain things to a Mech. Eng.

Thanks again,

Tim Flood
