Resistor Symbol, working, Color code and Types

The resistor is an electronic component restricts or limit the flow of current and divides the voltage in an electronic circuit. It is one of the most important passive components of an electronics industry because, without these components, active devices cannot process the electrical signals. Its main purpose is to provide a precise quantity of electrical resistance. In our previous articles, we explain, capacitors, types of capacitors, diodes in detail. In this article, we are going to explain resistors, resistor color coding, types of resistors in detail. Resistors Basics: Resistors mainly added to those circuits where they complement the active …

Bridge Rectifier Circuit, Operation, Characteristics & Advantages

Full wave bridge rectifier is another type of full wave rectifier used to convert an alternating current input into a direct current output. In a bridge circuit configuration, it comprises of four diodes that provide the same polarity of output for either polarity of the input. The main feature of this diode bridge which makes it more efficient than centre tap rectifier is its polarity i.e. the polarity of output is same as that of input. In our previous articles, we explain rectifier, half wave rectifier, Efficiency equation of half wave rectifier, efficiency equation of full wave rectifier etc. In …

Full wave Rectifier Efficiency Equation and Applications

Full wave rectifier basically uses both half cycles of the applied AC voltage and converts an AC voltage into a pulsating DC voltage. In full wave rectification, one diode conducts during one half-cycle while other conducts during the other half cycle of the applied AC voltage. It has some advantages over half wave rectifier like it has high average output DC voltage and has much fewer ripples resulting in the smoother output waveform. In our previous article, we explain Rectifier, half wave rectifier efficiency, diodes, p-n junction etc in detail. In this article, we are going to explain the mathematical …

Gallium Oxide: Semiconductor material with improved Heat conductivity

According to the recent work by Flosfia, a start-up in Kyoto, gallium oxide is one of the best semiconductor material with improved heat conductivity. The electronic component made from these type of material easily passes the electricity through power supplies, inverters etc are cheap and capable of handling high voltages. For the movement of electrons from the valence band to the conduction band, bandgap plays a vital role. Gallium oxide devices have approximately 5eV bandgap higher than that of silicon carbide ( 3.3 eV ) or gallium nitride (3.4 eV) which makes it more efficient. Due to the higher band …

Half Wave Rectifier Efficiency Equation and Applications

This is third chapter in Rectifier series. In the last two chapters we have covered the basics of rectifiers, and Half wave rectifier. Though we have covered various properties in our last article but kept aside a mathematical derivation of half wave rectifier efficiency equation. Because we think it needs to be explained separately. In this article, we are going to learn to calculate the equation of efficiency of half wave rectifier and about its various applications in detail. Before learning ahead, let’s have a little recap about the working of a half-wave rectifier. In Half wave rectifier, the diode …

Half wave Rectifier Circuit, working, operation and characteristics

We have covered the basics of Rectifier and its types in our previous article. Now we will learn about each type of rectifier individually. In this article, we will cover all about half wave rectifier. As we have read that there are mainly three types of rectifiers, namely half wave, full wave, and center tapped. This classification is done keeping in mind whether it uses full AC voltage waveform or half. Keep this point in mind while going through the rest of the article. What is Half Wave Rectifier? Half Wave Rectifier Definition can be given as: A Half wave …
