An op-amp comparator in a firing circuit can produce waveforms at the output of up to 28 V peak-to-peak without any distortion. An inverse cosine-based firing circuit with a voltage range from +14 to -14 (reference voltage) is used to produce a gating signal for the SCR at the desired delay angle. if the reference voltage is 5.92 volts, the delay angle (in degrees) would be:
