A Half Baked Idea Re-Envisioned

[tinman]

Well,the ringing up,instead of ringing down is interesting.

The only thing i can see ATM that may be an issue,is the fact that you are using ideal inductors ATM in your sims. It will be interesting to see how things change once you add in the inductors resistance values.

I would give the circuit a shot,but 1H inductors are very large,and would be hard to get here in OZ.
1H would be around the value of a MOT transformer--maybe i have a couple of them lying around at that value ?.

Keep up the good work.

OK,MOTs no good with the 2N5550.
The 2N550 has a max current of 300mA.
The MOTs i have are about .6ohms in resistance.
So,even at just 1v,we are looking at 1.66 amps at peak
I see smoke happening.

Looking into plan B

You may want to try a square wave to switch on your transistor,as it looks to me that it is not switching on cleanly,which can lead to transistor failor.

See the screen shot below of one of your scope shot's.
We can see the transistor starts to conduct,then drop off again before switching on cleanly.
This is due to the transistor being switch on by a sine wave.
