Re: [TCML] Primary/Sec. Frequency



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

Tim,
You want the primary frequency a little under the secondary frequency, maybe
3 to 4 % on a small coil. The reason is the streamers on the toroid have
capacitance and when the streamers form, they drop the secondary frequency
down a little bit. So by tuning the primary low to start with, they should
hopefully end up both about the same.

Is there a proper relationship between the primary output frequency and the
secondary output frequency? I did check the archives, with no luck.

Thank you.
