A full-wave bridge rectifier is constructed using 4 germanium diodes, each with a forward voltage drop of 0.3 V. The rectified waveform is described by the function vout(θ) = Vs sin θ - 2 VD where θ = sin-1 (2VD/Vs). Use integration to determine the exact average value of Vout for Vs = 1.5, 2, 2.5, 3, 3.5, 4, and 4.5 V (using Excel or Matlab will speed up this process considerably). Then use the estimation formula (0.636 Vs - 2 VD) to determine the average value for each value of Vs above and find the percent difference between the exact and estimated values for each Vs value. At what value of Vs does the percent error become greater than or equal to 5%?
Vs = 1.5 V
Vs = 2V
Vs = 3V
Vs = 2.5V

4.70 A full-wave bridge-rectifier circuit with a 500-22 load operates from a 120-V (rms) 60-Hz household supply through a 6-to-1 step-down transformer having a single Secondary winding. It uses four diodes, each of which can be modeled to have a 0.7-V drop for any current. What is the peak value of the rectified voltage across the load?
