Firing Angle in Switching Regulator Formulas

Firing Angle is the Angle of Delay Between the Zero Crossing of the AC Voltage Waveform and the triggering of the Thyristor. And is denoted by α. Firing Angle is usually measured using the Radian for Angle. Note that the value of Firing Angle is always negative.
