Peak Inverse Voltage of Diode

Peak Inverse Voltage or PIV is the maximum voltage appearing across the p-n junction diode when it is non-conducting. A diode do not conducts when it is reversed biased. This means peak inverse voltage is the maximum reversed biased voltage across the diode terminals when it is put in a circuit. Every diode has a … Read more

Center Tapped Full Wave Rectifier

A Center Tapped Full wave Rectifier is a circuit which makes unidirectional flow of current through the load during the full cycle of input voltage. Two diodes are so connected across the terminals of center tapped transformer secondary terminals that one diode conducts for positive half cycle and another diode conduct for negative half cycle … Read more

Calculation of Current through a Diode

Current through an Ideal Diode: The diode equation gives an expression for the current through a diode as a function of voltage. The Ideal Diode Law, expressed as shown below   Where, I = the net current flowing through the diode I0 = Reverse Saturation Current V = applied voltage across the terminals of the … Read more

Difference between Snubber Circuit and Crowbar Circuit

As we know, both Snubber Circuit and Crowbar Circuit is used for protection against Overvoltage using Thyristor but they way they protect the Thyristor has some difference. Crowbar Circuit: Power supplies are normally reliable, but if they fail then they can cause significant damage to the circuitry they supply. To protect against this it is … Read more

Step Potential and Touch Potential – Must Read

Step potential is the voltage between the feet i.e. one step of a person standing near an energized grounded object. Touch potential is the touch voltage between the energized object and the feet of a person in contact with the object. It is equal to the difference in voltage between the object and a point … Read more

Avalanche Breakdown of Thyristor

First we will describe what avalanche breakdown is. Avalanche breakdown occurs at p-n junction which is moderately doped and has a thick junction means have depletion layer width high. Avalanche breakdown occurs when we apply high reverse voltage across the p-n junction. As we apply more and more reverse voltage across the junction, the electric … Read more

How Ferrites Suppresses Interference?

Most of us use laptop / mobile and we charge our laptop daily by using their charger. But did you ever notice the round portion on the charger as shown in figure below. Did you ever think of what is that round portion? The round portion as shown in the figure is Ferrite used for … Read more

Difference between DC-DC Booster and Chopper

 DC – DC Booster: Booster converter is a combination of Transistors, diodes, and/or inductor or capacitor. The combination of active electronic elements (diodes and transistors) provides a DC voltage step up (say 1.5 to 9 v) while the combination of passive elements acts as a filter to reduce ripples. Its basic function is to step … Read more
