Hi RS,
That's pretty interesting!
Questions:
1. Does this only happen with an inductive load (coil)? How about with a majority resistive or capacitive load?
(Looks something like current lag in an inductor.)
2. Where is the current shunt located? Between emitter and ground? Between collector and coil/diode junction? Between coil and battery?
3. Is this the result of negative resistance in the barrier as holes and electrons migrate toward each other? Is this caused by a reverse avalanche phenomenon even though the collector is still positive compared to the emitter? Does this happen in both rotored and solid state modes?
4. In your drawing the time function begins at (I assume) the exact time the .6 volt barrier function is reached and the full supply voltage appears across the coil?
Sorry for all the questions. Just trying to figure out if this is due to inductive reactance, trigger current, or some other phenomenon.
