WebAngle β = 180° − α is called the angle of advance and angle γ = 180° − α − u =β − u is called the margin angle. As the angle of delay α is increased (angle of advance β decreased), the output voltage decreases, as seen in Fig. 13 (For simplicity, the commutation angle is neglected in Fig. 13 .) WebDec 2, 2024 · My guess on how the firing angle increases: I actually calculated this circuit's firing angle and got 95 degrees!
