Don stated that the Gating was a hand tuned part of the GMS... so once set its not messed with... its part of tuning??? ~Russ
I was wondering, looking at Russ his video about the SM VIC ,where he has unipolar voltages at the open VIC coils for the resonance cell, how it was pulsed.
Looking at the pulse signal in the Dealership Sales Manual, how Resonant Action is done, did you see the pulses he used in the figure? p60 Fig.16.
SM pulsed it lets say, 0Vdc to Va dc, but when he wants resonant action he pulses 0Vdc to Vn dc. So the gating window where amplitude is higher he adjusted it to get Resonant Action. This simultaneous with the pulse frequency for the coil resonance.
The patent circuit driver does not do this, only 0V dc to Va dc. at the TIP120 transistor. Gate adjust the 0V to Va voltage pulse with?
When GATE is ON, voltage amplitude should go up to a higher pulse voltage level setting (gas pedal) gas production (step charge);
GATE OFF, amplitude is pulse resonance maintained (no step charge).
See circuit "voltage amplitude control".
Have you looked into this?
