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)
