At the Cheesehead, I was running the mid size DRSSTC and Steve Ward was standing under his big DRSSTC, we must have been close on the fo because his coil arced over to his head, whooooops. Dang that hurts.

Oh, I hope he wasn't too hurt. Take care guys suprised

I'm going to power some DC loads too; a bridge of diodes works well as long as load is connected, but resonator base acts like a current source and would blow it up without load!

Going to need to design some kind of hysteresis-controlled circuit which will short the resonator to ground once a cap is charged!

The coil is running quite < 100W on the pic, yes it's interesting to see how much power can be transferred even with streamer load!

This is my new H bridge, it`s a double sided PCB mounted on top of a 5600uF cap. The IGBT`s is HGTG20N60A4D.

I hope my low inductance layout work, because I didn’t make room for a snubber cap...

It’s for a DRSSTC I’m making smile

Cool H-bridge Daniel,

It kind of reminds me of Steve Conners 1st early DRSSTC bridge.
Hopefuly you won't need that snubber cap,
So....what are the specs for your coil?
and what driver do you intend to use?

All the best,

Mel

The reflected IR light washes out the reflected green visible light from the plant's leaves. It also makes skin look kind of translucent.
