The purpose of the rectifier is to convert alternating current (AC) to direct current (DC). As in the half-wave rectifier, the rectifier output DC consists of AC components or ripples in it. To overcome this filter can be connected across the load so that the ripples can be reduced but this kind of circuitry is suitable for low power required applications. To overcome the problem of the half-wave rectifier, the model of the full-wave rectifier circuit is developed. In full-wave rectifier, full … [Read more...]
Half Wave Rectifier : Working and Its Characteristics
The purpose of the rectifier is to convert alternating current (AC) to direct current (DC) that is to undergo rectification. As the diode used in this process allows the flow of current in a unidirectional manner. Basing on this property of the diode the various types of rectifiers are designed. From the number of diodes used in the circuit the classification of rectifiers is done. Basically, the half-wave rectifier can be designed by using a single diode termed as single-phase rectifier. But if … [Read more...]
Different Types of Rectifiers & their Working Compared
The basic p-n junction diode that is used for the conversion of AC to DC can be referred to as a rectifier. This process is known as rectification. Based on its efficiency of converting AC to DC these rectifiers are chosen so that it can satisfy the essential requirements of the power supply unit in the electronic systems. Various basic electrical or electronic components are preferred in order to design rectifiers it can be diodes, MOSFET’S, etc. Considering the suitable application essential c … [Read more...]
What is a Rectifier : Working and Its Applications
A basic diode has various applications it includes rectifiers in it as well. Rectification can be done through the basic diode. It may be current or voltage the AC values will be converted into DC. The basic property of the diode is that it can establish the path for the flow of current in one direction that is possible during forwarding bias. However, during reverse bias, the diode remains in non-conducting mode. It doesn't participate for the establishment of the path for the flow of current. … [Read more...]
Difference Between Drift Current and Diffusion Current
In a semiconductor either it may be p-type or n-type there exists some of the majority and the minority charge carriers. As the p-type and n-type present on a single crystal at the center, there is the formation of the p-n junction. The basic device formed because of the above process is p-n junction diode. We cover the basic differences between Drift Current and Diffusion Current below with comparison table. In the p-n junction diode if it is doped non-uniformly then there exist movement of … [Read more...]
Diffusion Current Explained with Diagram & Derivation
Diffusion current is mainly generated in semiconductors.The doping done in the semiconductors is non-uniform. In order to achieve uniformity, the flow of charge carriers takes place from higher concentration area to lower concentration area. It is referred to as diffusion. This process generally doesn't occur in conductors. Fick's law well describes the diffusion of flux from that the thesis is derived for the diffusion of electrons as well as for holes. The necessity of the diffusion … [Read more...]
Basics of PNP Transistor – Construction, Working & Circuit Diagram
PNP Transistor is a type of bipolar junction transistor. This transistor also consists of three terminals known as collector, emitter, and base. While discussing its structure in comparison with N-P-N it is completely different. Instead of two n-types here it is two p-type semiconductors are involved in the process, whereas the separation region between these types is due to the n-type. The majority participation of the carriers in this type of transistor is due to the holes because two … [Read more...]
Darlington Transistor Working, Pair Configuration and Applications
Darlington transistor is a pair of transistors that are connected in such a way that it enhances the features of the respective application. This transistor pair is invented by Sydney Darlington. It is formed in such a way that either two P-N-P or N-P-N transistors are connected so that the emitter of the one transistor is connected to the base of the other transistor. Both the transistors interlinked so that one can act as input other can refer to as output one. The output of the transistor … [Read more...]
Bipolar Junction Transistor : Working, Types and Its Applications
The invention of the Bipolar Junction Transistor (BJT) is done in the year 1948. Transistors are the basic electronic devices that are formed because of the combination of the diodes that are referred to as bipolar junction transistor. These bought the revolutions in the modern electronic system. These inventions of transistors are the major reasons for the replacement of vacuum tubes. Individual diodes of the junction p-n that are connected back to back lead to the formation of the … [Read more...]
What is Zener Breakdown & Avalanche breakdown & their differences?
In a basic semiconductor, a junction is formed due to the interaction between p-type and n-type. This junction can be dope heavily or lightly based on circumstances. As it is already known that a basic diode that is of junction p-n can conduct during forward bias. Once the stage of reverse bias entered it cannot conduct and some breakdowns arise. These are mainly due to the multiplication of the carriers as well as due to the doping concentration made high at the junction. There are two types … [Read more...]
