- The firing angle (α) is the point at which the SCR is triggered (turned on).
- The extinction angle (β) is the point at which the SCR turns off (due to current dropping below the holding current or due to forced commutation).
- The conduction angle(γ) represents the duration for which the SCR remains conducting.
Since conduction starts at α and ends at β, the conduction angle is given by:
Conduction angle = β - α
