Calculate the ripple factor of a full wave 6 phase rectifier

Calculate the ripple factor of a 6 phase half wave rectifier.

ripple factor of a full wave 6 phase rectifier = square root [(form factor)² -1] = square root [(1.11)² - 1]= 0.4817

ripple factor of a half wave 6 phase rectifier = square root [(form factor)² -1] = square root [(1.57)² - 1]= 1.21
