I can set deadtime by using two methods.
- No interlock (bridged certain pair of contacts). I could use turn-on and turn-off resistors for every gate. The more resistance, the slower is the turn on or turn off. Turn on and turn off start occurring simultaneously.
- Interlock. That's the mode with guaranteed deadtime. I can set deadtime by putting a resistor in the interlock contacts (same contacts as in 1). Set from 0.9 to 10 uS. I suspect that I could go lower as well.
As I said, I do not want deadtime. I want the bridge to short. So I used method 1 and gate resistors.
I f***ed it up in the sense that while the bridge does short and never opens, the short time is too much. That makes for too much current losses. I will need to go back and adjust the turn off resistors, I think that I will set them to perhaps 47 ohm instead of the present
100 ohm.I will make a separate post about it to s.e.d.
