Solution of the Problem 64-7 . Let's start solving this problem by analyzing the zener V Z2, where we know that the current in the load is variable, so the current through the zener is also is variable.Consulting the theoretical part we see that we are facing CASE 2.Then we will use the equations eq. 64-10 and eq. 64-11.
Solution of the Problem 64-9 . From the circuit we conclude that when 0 ≤ V i < 3.6 the diode D 1 is cut off, that is, no conduct. In this case, as there is no current flowing through the circuit, both D 2 and D 3 are cut, consequently the output voltage V o = 0.As soon as the voltage V i exceeds the value 3.6 volts, the diode D 1 starts conducting, and from that moment on there will be a ...

Solution of the Problem 64-10 . From the circuit, with the polaridad of V i, we see that when D 3 conducts like a zener diode, D 1 will conduct like an ordinary diode. Thus, considering the null currents in the circuit, the voltage on D 3 will appear on the output, ie, V o = - 3.6 volts.Note that D 1 will conduct simultaneously with D 3, when V i = - 3.6 - 0.65 = - 4.25 volts.
Numerical Problems. 1. The given circuit has two ideal diodes connected as shown in figure below. Calculate the current flowing through the resistance R 1 [Ans: 2.5 A] Solution: Barrier potential for ideal diode is zero. The diode D 1 is reverse biased, so it will block the current and diode D 2 is forward biased, so it will pass the current.

Having defined the Zener voltage V Z = −v B.In Figure 3, we report the trend of this function which however does not cancel for v D = 0, and this destroys the possibility of connecting the graph with the branch in the range v D > 0. This circumstance does not create problems because we are studying the behavior of the diode in reverse bias.
