Average and RMS Value of single-phase half-wave rectifier

Let

Vm = maximum value of transformer secondary voltage

Vs =rms value of secondary voltage

VLM =maximum value of load voltage = Vsm – diode drop – secondary resistance drop

VL = rms value of load voltage

IL = rms value of load current

VL(dc) =average value of load voltage

IL(dc) = average value of load current

ILM = maximum value of load current

RL = load resistance

RS = transformer secondary resistance

rd = diode forward resistance

now,

R0 = RS + rd
ILM = Vsm – VB /(RS + rd) + RL
        = Vsm –VB  
VLM = ILM . RL
VL(dc) = VLM/π = 0.318VLM
IL(dc) = ILM/π = 0.318ILM
IL = ILMn/2 = 0.5ILM = 0.5VLM/RL
