Verification of Zener Voltage Regulation Phenomenon Using Remote Engineering

Abstract

Voltage regulators play an important role in maintaining constant output voltage across electronic circuits. They are also used for impedance matching. Zener diode is most commonly used semiconductor device in designing voltage regulator. Stabilizing circuits whose essential parts contain Zener diodes are used for protection of circuits from over voltages. It is very important to study the characteristics of Zener diode for the designing the stabilizing circuits and voltage regulators as well as clippers. In this paper Zener voltage regulation phenomenon is verified using the Remote Engineering. The entire setup of the voltage regulator circuit is controlled remotely through mobile or personal computer. This can be achieved with the help of Arduino. Arduino is a traditional tool used in many electronics circuits mainly involving Embedded systems, Internet of things and Remote Engineering as well. The voltage regulation phenomenon of the Zener diode has been a very important experiment for the beginners in electronics engineering. However this phenomenon can also be verified using the remote engineering. The student can go through the circuit using his/her mobile or laptop. The student can watch the entire setup in web camera and variation in the output voltage is displayed. The student also has the tendency to control the input voltage and observe the constant output voltage.
