PN junction Diode plays a vital role in our electronic fields, because of their unique property (current flows in only one direction) they are used in many electronic or electrical circuits like rectifiers, switches, clippers, clampers, voltage multipliers.
This article is based on the diode clamper circuit, working of positive and negative clamper circuits and the applications of clamper circuits using different waveforms and circuit.
A major difference between Diode and Zener Diode is that a PN junction diode can operate in forward bias only whereas a Zener Diode can operate in Forward bias as well as in reverse bias. There are a number of differences between a normal diode and a Zener diode and in this article, we will cover them one by one.
Tunnel Diode is invented by researcher Leo Esaki in 1957 he received the Nobel Prize in 1973 for discovering the electron tunneling effect used in these diodes. Therefore, it is sometimes known as Esaki Diode, he discovered that by adding high impurities to the normal PN junction diode a diode can exhibit negative resistance in the forward bias. A diode with these high impurities can be used for very fast operation, well into the microwave frequency region, by using quantum mechanical effects.
This article is based on the Light Emitting Diode, working and operations of Light Emitting Diode (LED) and the applications of Light Emitting Diode (LED).
Zener diodes have major application for being used as a voltage regulator for providing stable reference voltages for use in power supplies, voltmeters, and other instruments. In this article, you will see how the Zener diode maintains (regulate) a nearly constant dc voltage under the proper operating conditions.
welcome to this article, In this article, we are going to learn about FULL WAVE RECTIFIER- Center-Tapped and Bridge Rectifier as we Learned about Half-wave rectifiers previously.
Half Wave Rectifier
A Half wave rectifier is a Circuit which converts Ac voltages to Pulsating Dc Voltages. Let us Observe how this Half wave rectifier converts Ac voltages to Pulsating Dc, I have illustrated the process below:
