This is the assembly that will be the actual gatedrive in my TIG inverter. The center of it is the signal generator board (prototype board with integrated circuits). It has screws that are adapters for DC power in, signal out to Semikron gate driver boards, as well as adapters for the potentiometer controlling cleaning vs. penetration, and also an adapter for selectable capacitor. For now I decided to settle on fixed values, 75% penetration and 250 Hz frequency. Since I have these screws, adding external controls will be easy.
The signal generator assembly has been tested.
