In order to convert an AC voltage source to a DC voltage sou

In order to convert an AC voltage source to a DC voltage source, the AC voltage must be rectified and smoothed out. Assuming you have a full wave rectifier (Figure 1), identify which one of the following smoothing circuits (Figure 2) gives you the smoothest DC output, by simulating the smoothing circuits where R=100kohm, C=80nF, R_1=300 ohm, L_1 = 1 mH, C_1=253 muF. Assuming that the load resistor is R_L = 100 kohm.

Solution

by the figure(2) 1 is gives smooth DC voltage due to absence of inductance
