Frequency Component of single-phase center-tap full wave rectifier
As in the case of the Half-wave rectifier, the output of a full-wave rectifier also consists of (i) a dc component and (ii) a number of ac components which form the ripple. The Fourier series for rectifier output voltage is
VL = VLM(2/π – 4 cos2ωt/3π – 4 cos4ωt/15π – 4 cos6ωt/35π - ………….)
As seen, VL(dc) = 2VLM/π; VL1 = 4VLM/√2*3π, VL2 = 4VLM/√2 *15π etc
VL(ac) = √(VL12 = VL22) = √(4VLM/√2 *3 π)2 + (4VLM/√2 *15 π) = 0.305 VLM
Similarly, IL(ac) = Ir(rms) = √(IL12 + IL22) = 0.305 ILM
Here,
VLM =maximum value of load voltage = Vsm – diode drop – secondary resistance drop
VL = rms value of load voltage
IL = rms value of load current
ILM = maximum value of load current
IL(dc) =average value of load current
