3.60 The circuit in Fig. P3.60 implements a complemen- tary-output rectifier. Sketch and clearly label the waveforms of vo and vo. Assume a 0.7-V drop across each conducting diode. If the magnitude of the average of each output is to be 15 V, find the required amplitude of the sine wave across the entire secondary winding. What is the PIV of each diode?

Text 3.66. Piecewise linear models should be used. Part (a) assumes you assume the diode switches from OFF to ON when the diode voltage is zero volts Part (b) of problem assumes you use the diode model that just includes a 0.65 volt battery when the diode Witshes from OFF to ON. The best systematic approach is to draw out each circuit and then look for any potential contradictions with the diode model and circuit when you assume a diode is either ON or OFF. Sketchina piece-wis linear I-V characteristic is one approach to piece-wise linear problems. Prepare a table to summaize your reis. 1. 3.66.

Consider an idealized diode with a reverse saturation current 0.01 mA and an abrupt turn-on voltage of 0.7 V (assume no breakdown and operation away from the knee of the diode curve). For the circuit shown, both resistors are 100 2, the constant source is Vp = 5 V, and the time-dependent source is V3 = 20 sin(at) V. Calculate (a) the peak positive voltage V and the associated current through the diode and (b) the peak negative voltage V and the associated current through the diode. Rulamting R Vs + > KHI
