from a wall outlet), you must first convert it to the peak voltage Vmcap V sub m
The input to a rectifier is typically a sinusoidal AC voltage defined as . If you are given the RMS value of the AC input (e.g.,
Vm=Vrms(input)×2cap V sub m equals cap V sub r m s open paren i n p u t close paren end-sub cross the square root of 2 end-root 2. Determine Average (DC) Voltage
Vdc≈Vm−Vdπcap V sub d c end-sub is approximately equal to the fraction with numerator cap V sub m minus cap V sub d and denominator pi end-fraction 4. Calculate RMS Output Voltage
