A Capacitor filter is used at the output across the load in order to minimize the ripple factor of the output voltage. The expressions of the average output voltage VDC and the output AC component VAC are given below. If R = 0.5kΩ and the single phase bridge rectifier supplied from a 120V - 60 Hz sinusoidal source, then the capacitor value that will maintain the amount of the output ripples to less than 5% would be equal to:
VDC=Vm((4fRC−1)/4fRC)
VAC=Vm/(4√2fRC)
VDC=Vm((4fRC−1)/4fRC)
VAC=Vm/(4√2fRC)
