Hello guy's,
is it a problem if i'm going to use a topload on my EVR 4mhz coil,
I wan't to use a topload (toroid) because it looks better, ...

Just use an iron-powder toroid. High permeability ferrite will saturate due to the DC supply current when used as an RFC unless it has a big air gap ...

If you getting eddy current in a toroid wouldn't common sense tell you that you secondaries too short?
Even anyways in a sgtc the pulse is so cru...

...Cs it seems to me that putting a large conducting toroid or sphere on the end of the coil effectively presents a shorted turn to the coil, albeit a ba...

The toroid only lowers the Q if it's made out of poorly conducting material. A good conductor like aluminium or copper will reflect the EM field inste...

Beautifully done. I need to find a case like that for the linear supply I'm building. I wound a custom 750VA 5 secondary iron toroid power transformer...

Well, you should always have another turn or so more than what you calculate for tuning and toroid experimentation. That extra turn will probably acc...

You will not cheaply find a suitable toroidal inductor for a high-power
low-voltage zvs due to conflicting requirements;
- many turns to produce t...
