Calculate the ripple factor of a full wave 6 phase rectifier

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

Solution

Ripple factor :   Ripple factor () may be defined as the ratio of the root mean square (RAMs) value of the ripple voltage to the absolute value of the dc component of the output voltage, usually expressed as a percentage. However, ripple voltage is also commonly expressed as the peak-to-peak value.

for single phase for full wave rectifier m = 1 ripple factor = sqrt of FF = sqrt of 1.11^2-1 = 0.483

for half wave RF = 1.21

then m = 6 RF = 0.042
