Presentation on Zener diode & Full wave rectifier - Overview

------------ PAGE 1 ------------ Welcome to our Presentation ------------ PAGE 2 ------------ Presentation on Zener diode and Full wave rectifier Course name - Analog Electronics I Course code - EEE223 ------------ PAGE 3 ------------ Contents . Zener diode . How it works . Symbol . Condition . Application of Zener diode . Bridge rectifier . Bridge rectifier with capacitor and without capacitor . Graph of bridge rectifier . Application of bridge rectifier ------------ PAGE 4 ------------ Zener diode . A Zener Diode is a special kind of diode which permits current to flow in the forward direction as normal, but will also allow it to flow in the reverse direction. Working principle : Zener breakdown Invention : Clarence Melvin Zener configuration : Anode and cathode ------------ PAGE 5 ------------ How it works . If it connected with forward direction it will work exactly the same as a standard diode. . when the voltage reaches the breakdown voltage ( V BR ), suddenly current can flow freely through it. . It keeps constant voltage . ------------ PAGE 6 ------------ Symbol of a Zener Diode Figure- Zener diode ------------ PAGE 7 ------------ Condition Breakdown condition of a Zener diode V N - V P . V Z ------------ PAGE 8 ------------ Application of Zener diode . Zener diodes are used in Voltage stabilizers ( or) shunt regulators ; . Used in Over voltage protection circuits ; . Zener diodes are used in clipping and clamping circuits especially peak clippers ; . They are used as Reference elements ; . Used in switching applications. ------------ PAGE 9 ------------ Full wave rectifier ------------ PAGE 10 ------------ Full wave/ H / Bridge rectifier A Full Wave Rectifier is a circuit , which converts an ac voltage into a dc voltage. ------------ PAGE 11 ------------ Circuit of Bridge rectifier ( without capacitor) ------------ PAGE 12 ------------ Bridge rectifier ( With capacitor) Figure- Bridge rectifier with capacitor ------------ PAGE 13 ------------ Bridge connection Graph With capacitor ------------ PAGE 14 ------------ Applications of Bridge Rectifier : . Because of their low cost compared to center tapped they are widely used in power supply circuit. . This can be used to detect the amplitude of radio signal. . Bridge rectifiers can be used to supply polarized voltage in welding. ------------ PAGE 15 ------------ Thank You All For being with us
