Peak Current of bridge rectifier

Instantaneous value of voltage applied to the rectifier is given as

VS = Vm sin ωt

If the diode is assumed to have a forward resistance of RF ohms and reverse resistance equal to infinity, then current flowing through the load resistance is given as

i1 = Im sin ωt and i2 = 0 for the first half cycle

and i1 = 0 and i2 = Im sin ωt for second half cycle

The total current flowing through tha load resistance RL, being the sum of currents i1 and i2, is given as

i = i1 + i2 = Im sin ωt for the whole cycle

Where peak value of current flowing through the load resistance RL is given as

Im = Vsm / (RF + RL)
