 Divyanshu Shekhar said: (Nov 23, 2016) First pulse => During the first pulse, the capacitor charges. The output voltage reaches, 12.64 V (63.2% of 20 V). Between first and second pulses => The capacitor discharges and the voltage decreases to 36.8% of the voltage at the beginning of this interval: 0.368 (12. 64 V) = 4.65 V. Second pulse => (20 - 4.65) V = 15.35 V. Between second and third pulse = > 0.368 (15.35) = 5.64 V. Third pulse => (20 - 5.64) v = 14.36 V. Between third and fourth pulse => 0.368 * (14.36) = 5.28 V. Fourth pulse => (20 - 5.28) V = 14.72 V. Between fourth and fifth pulse => 0.368 (14.72) = 5.41 V. Fifth pulse => (20 - 5.41) V = 14.59 V. => 14.6 V approx.
