i) The equation above contains really only three variables in it: Id, Vd, and T. All the other terms are constants. Since in most cases we assume temperature is fairly constant as well, we are really only dealing with two variables: diode current and diode voltage. Based on this realization, re-write the equation as proportionality rather than equality, showing how the two variables of diode current and voltage relate ii) Based on this simplified equation, what would an I vs V graph for a PN junction look like? How does this graph compare against the I vs V graph for a resistor? iii) When "P" and "N" type semiconductor pieces are brought into close contact, free electrons from the "N" piece will rush over to fill holes in the "P" piece, creating a zone on both sides of the contact region devoid of charge carriers.

In a Zener regulated DC power supply, the input to the regulator varies between 15 V and 19 V. The magnitude of the series resistor in the regulator circuit is 40 Ω, and the load draws a constant current of 100 mA at 9 V. Use the ideal Zener diode model.

A dc power supply is to be developed by employing an ac to dc converter as a power processing converter for 180 watts highly inductive load. The rms value of the input ac phase voltage is 230 V at 50 Hz frequency. Select a suitable rectifier circuit having improved ripple factor and power factor for this application. The output dc voltage is assumed (245). The output dc voltage should be multiplied with ‘0.5’ if it exceeds the 200 V.A dc power supply is to be developed by employing an ac to dc converter as a power processing converter for 180 watts highly inductive load.
