Quick Tips
My basic GDT design spreadsheet will help speed up the design process, but for a quick guide:
- Review the information in this design guide
- Get a core of the correct type
- Calculate minimum number of turns required to avoid saturation
- Calculate the magnetising current and the gate current
- Select the wire diameter (based on the amount of current) and wire type
- Wind the transformer
- Test with a small series resistor, increasing or decreasing the value to control the ringing
- Repeat any of the above steps as necessary until it works proper ;-)
