In the past i have made numerous sstc's, fullbridges for drsstc experiments, and for transformer driving. But i have never made a fullbridge solid state Tesla coil. I have some parts sitting around, so i decided to make a sstc.
It will have an optional interrupter with burst mode and seperate frequency and duty cycle control for both the interrupter and burst mode. It is quite mini-sstc esque. I always hated using an entire 74hc14 even though i only needed 2 gates (which reminds me, for Steve Ward's mini sstc you only need one gate). I also hated working with 555's, because the duty cycle has to increase and decrease when the frequency is changed. So, the interrupter and burst mode consists of 4 pots, 4 capacitors, and i believe 6 resistors and a 74hc14 and 2 actives.
The rest of the driver is the 2 74HC14 gates i need for buffering and the one i need because my gate drivers are all non-inverting. After that it goes to the two 4 amp peak TO-220 gate drivers. That may not sound so great compared to the ucc37322 with it's 9 amp peak, but my gate drivers (UC3710T) can push 1 amp steady state. Not to mention heat sinking ability.
This will all be built into an ATX power supply box with a built in RFI filter, with a large external heatsink for the final amplification stage (G27N120BN IGBTs) mounted onto the outside of the box. I can pretty much ensure the insides with be very disorganized, but i will be able to minimize the GDT leads to maybe an inch 'round-trip' one the secondary, and a cm or two primary lead length...
Process is slow due to assorted reasons, but if i where able to stick with things, i could get it running by tomorrow.
Here are some cruddy pictures for now. Hopefully you can figure out what each one is
