please could someone point me in a good direction, i have to look at thyristor (triac) firing circuits using phase control to vary the power to an AC load (lamp). Basicly a dimmer circuit, i have managed to find lots of info on dimmer circuits and constructed a reasonable working circuit.
But i cannot find a good source regarding how to pick/calculate the best value resistor and capacitor in the RC network used to move the phase angle to trigger my diac and then triac at the various degrees required. Also i am struggling to model it in multisim so any help in that department ould be appreciated.
Many thanks and any help would be appreciated
