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

V_L = V_LM(2/π – 4 cos2ωt/3π – 4 cos4ωt/15π – 4 cos6ωt/35π - ………….)

As seen, V_L(dc) = 2V_LM/π; V_L1 = 4V_LM/√2*3π, V_L2 = 4V_LM/√2 *15π etc

V_L(ac) = √(V_L1² = V_L2²) = √(4V_LM/√2 *3 π)² + (4V_LM/√2 *15 π) = 0.305 V_LM

Similarly, I_L(ac) = I_r(rms) = √(I_L1² + I_L2²) = 0.305 I_LM

Here,

V_LM =maximum value of load voltage = V_sm – diode drop – secondary resistance drop

V_L = rms value of load voltage

I_L = rms value of load current

I_LM = maximum value of load current

I_L(dc) =average value of load current
