I am planning to make my first SGTC and well first I want to start making the power supply for it, since I do not have an MOT and other types of high voltage transformers for 120Vac. and also take advantage to later make an RSSTC. But maybe not. I have a ferrite core taken from a small flyback, in the round part 11.5-11.6mm, 66mm high, rectangular part 11.5-11.6mm x 9mm, 10mm at the top and bottom and a free space for the winding of 14.5x47mm such time 46mm without the spacers.

After several hours on the Internet I have not found much information about the calculation and design for this type of font. What I have seen out there is that they only do it "randomly" without much explanation of why.

I plan to use it with 120Vac or an autotransformer that I found from a UPS that I took apart and it seems to use enameled aluminum awg 10 wire
1. The driver to control the transformer, what type of configuration is suitable for the type of transformer that is going to be used, ZVS type or a Half bridge? advantage and disadvantages of each? What voltage should it run at for optimal operation?
2. How are the calculations carried out to wind the transformer? Does it depend on the core material? How can I know the type of core material? What difference does it make if I use an air gasp in the core or not? Which way is best to wind the high voltage side of the transformer, layer by layer insulated with paper or segmented for each amount of kV, I plan to place it inside oil.
3. Depending on which driver configuration is chosen, how can I perform the calculations and design of the driver for the transformer used?
