Rectification Flashcards
What is rectification?
Rectification is the process of converting an alternating current to a direct current with the aid of a diode
What is the major advantage of full-wave rectifier over half-rectifier
There is less ripple produced in full-wave rectifier when compared to the half-wave rectifier
Half wave rectifier
It transform AC voltage to DC voltage. A half wave rectifier circuit uses only one diode for the transformation. A half wave rectifier is defined as a type of rectifier that allows only one half cycle of an AC voltage waveform to pass while blocking the other half cycle.
What are the components of a half wave rectifier
A diode
A transformer
A resistive load
When the diode is forward biased and reversed biased what are the implications
Forward biased implies that is acts as a closed switch
Reversed implies that it acts as an open switch..
Smoothing
The process of using reservoir capacitor to remove the remain fractions of AC to produce full DC.
What is a diode
A diode is a two terminal device consisting of a P-N junction formed either in a germanium or silicon crystal.
What is an inverter
An inverter is a device that converts DC power into an AC power.
What is a P-N junction diode
Is a one way diode that offers low resistance when forward biased and behaves like an insulator when reversed biased.
What is the work of a filter
A circuit that converts a pulsating output from a rectifier into a steady output is called a filter.
Filter circuits are used to minimise the ripple content in the rectifier output.
Full-wave rectifier
A full-wave rectifier is defined as a rectifier that converts the complete cycle of alternating into pulsating DC
Forward biased occurs when
The voltage across a diode permits a natural flow of current
