Secondly i would also like to thank my parents and friends who helped me a lot in finalizing this project within the limited time frame.


Aim

Aim of this project is to demonstrate the working half wave rectifier.


Introduction

A half wave rectifier is a type of rectifier which converts the positive half cycle of the input signal into pulsating DC output signal. The half wave rectifier is the simplest form of the rectifier. We use only a single diode to construct the half wave rectifier.


Working of half wave rectifier

When high AC voltage  is applied, the step-down transformer reduces this high voltage into low voltage. Thus, a low voltage is produced at the secondary winding of the transformer. The low voltage produced at the secondary winding of the transformer is called secondary voltage (VS). The AC voltage or AC signal applied to the transformer is nothing but an input AC signal or input AC voltage.

 

The low AC voltage produced by the step-down transformer is directly applied to the diode.

Advantages of half wave rectifier

  • We use very few components to construct the half wave rectifier. So the cost is very low.
  • Easy to construct

Disadvantages of half wave rectifier

  • Power loss The half wave rectifier either allows the positive half cycle or negative half cycle. So the remaining half cycle is wasted. Approximately half of the applied voltage is wasted in half wave rectifier.
  • Pulsating direct current The direct current produced by the half wave rectifier is not a pure direct current; it is a pulsating direct current which is not much useful.
  • Produces low output voltage.

     Material required

  • Center tapped transformer:- When an additional wire is connected across the exact middle of the secondary winding of a transformer, it is known as a center tapped transformer.
  • Diode:- A diode is an electronic component with two electrodes. It allows electricity to go through it only in one direction.
  • Resistor:- The resistor is a passive electrical component to create resistance in the flow of electric current.
  • LED:- An LED produces light when electricity flows through.
  • Soldering Iron:- To solder the various components used in this project.
  • Capacitor:- A capacitor is a two-terminal, electrical component. Along with resistors and inductors, they are one of the most fundamental passive components we use.
