Hello All.
I can't understand how this triac is trigger to enable the on state.
But the important is the power side
When the MOC3021 is on off state.
Ig = (V - Vg)/ (R4 + Rload )
where Vg is Vgate - Vmt1
Ig should be:
Ig < Igt
MOC3021 is on:
Ig' = ( (V - Vg)/ (R4 + Rload ) ) + ( (V- Vg)/(1/sC + R6 + Rload) )
Ig' should be:
Ig '> Igt
Is this analysis correct?
