This document provides an overview of analog electronics topics including semiconductor diodes, bipolar transistors, single and multi-stage amplifiers, and field effect transistors. It specifically discusses diodes and how they can be used as rectifiers to convert AC to DC power. There are three main types of rectifiers: half-wave, full-wave, and bridge rectifiers. The document explains how each type of rectifier works and its peak inverse voltage rating in relation to the maximum voltage of the power source.

3. Semiconductor Diode
A diode is fabricated from a p-n
junction. Semi-conductors such as
silicon or germanium can be “doped”
with small concentrations of specific
impurities to yield a material which
conducts electricity via electron
transport (n-type) or via holes (p-type).
When these are brought together to
form a p-n junction, electrons (holes)
migrate away from the n-type (p-type)
side.

5. Diode as a Rectifier
Rectifier is a device which convert the ac supply to dc supply. It use in
mobile charger, battery charging system and etc.
There are some classification of rectifier as;
1. Half-wave rectifier
2. Full wave rectifier
3. Bridge rectifier

7. Half Wave Rectifier

8. Full Wave Rectifier

9. Bridge Rectifier

10. Peak Inverse Voltage
In semiconductor diodes, peak reverse voltage or peak inverse voltage is
the maximum voltage that a diode can withstand in the reverse direction
without breaking down or avalanching.If this voltage is exceeded the
diode may be destroyed. Diodes must have a peak inverse voltage rating
that is higher than the maximum voltage that will be applied to them in
a given application.
Half Wave Rectifier’s PIV=Vm
Full Wave Rectifier’s PIV=2Vm
Bridge Rectifier’s PIV=Vm
