As a common part of all the electronic power supplies circuits, rectifier circuit provides DC power supply from available AC supply for proper function of electronic equipments. Depends on the type of application, this rectifier configuration and types are varied like diode rectifiers and phase controlled rectifiers, etc. but each one has their own advantages and disadvantages. The rectifier circuit can be implemented with different solid state electronic or electrical components like diodes, SCRs, MOSFETs and so on. Upon these components used rectifier operation is varied in order to get the required output. Before going to know its types let us know what is a rectifier in brief. [Read more…]
As a rapid prototyping tool in various measurement and control engineering applications, LabVIEW allows to implement a wide variety of real-world relevant laboratory experiments. Latest projects and experiments in engineering applications are used to simulate the actual job conditions which are bound to a specific hardware and circuit components. In spite of this, we can create the virtual prototype models of real-time systems by incorporating LabVIEW programming language to engineering projects and experiments. Even though we can create and control various projects using LabVIEW with dedicated data acquisition (DAQ) hardware, more economically and to reduce the feasible time constraints, virtual laboratories and projects are introduced.

In these days, the major concern for many people is about the amount of electricity consumed in homes, offices, industries, and so on. Energy meter is an electricity measuring device, which records electrical energy consumption over a specified period of time. Thus, the accurate measurement and record of electrical energy consumption has greatly impacted the usage of energy meters. [Read more…]
A Computer is an electronic machine which is being used for many applications. The computer major parts are input devices, CPU and display monitor. There are various input devices such as mouse, keyboard, scanner, webcam and so on. But, the computer mouse is considered as a major input device which is used frequently while working with computer or laptop. Mice are classified based on different criteria. A few types of currently available mice are a PS/2 connector mouse, USB mouse, Wireless tilt wheel mouse, 3D mouse, Mechanical mouse and so on. As a special case we discuss about the wireless tilt wheel mouse in this article.
In general, while walking or running we can observe the inward roll of the foot, which is called as pronation or eversion and it is measured in terms of the degree of inward roll. But, we can look at pronation even in other terms like when foot pushes off at the end of each step or at the end of the gait cycle. The pattern in which animals or human beings move their limbs during many manifestations such as running or walking or swimming etc. is called as gait. The pronation has to be measured to avoid the underpronation and overpronation, as these may lead to foot, knee, ankle and hip injuries. But, how to measure pronation? [Read more…]
In our day-to-day life we frequently got used to listen the news, music and other programs through FM radio station by tuning to our favorite bands with wireless transmission and reception of data. Edwin Armstrong developed super-regenerative circuits and super-heterodyne receiver, which made radio broadcasting successful. In 1933, a revolutionary change was made by Armstrong in the broadcasting business with FM radio. The entire system depends on the FM radio transmitter to transmit the data from the transmitter end to the receiver end. But, are you aware of working of these FM transmitter and receiver circuits?

For improving productivity and the quality of end products, most of the industries are equipped with advanced control systems by adopting complex control strategies for both critical and non-critical applications.
These modern industrial control systems are usually made to produce one or more control actions depending on the application implemented. This article describes the basic control strategies used in industrial control system and its types with a brief explanation. [Read more…]
Nowadays electricity is considered as one of the basic needs of human beings. The conventional power transmission system uses transmission lines to carry the power from one place to another, but it is costlier in terms of cable costs and also there exists a certain transmission loss. One maintainable technology leading this charge is a wireless power transmission (WPT) . It is also known as inductive power transfer (IPT). [Read more…]
Nowadays home automation system is an emerging technology that operates the electrical appliances and loads remotely by using advanced controllers with proponent communication technology. This is an advancement of the conventional mechanization process wherein human efforts are needed to operate the electrical devices or appliances . Control capability is more sophisticated with this automation ranging from low level to high level control. So let us look at this topic in brief with practical examples. [Read more…]
Power supply is an electronic circuit that is used for providing the electrical power to appliances or loads suchas computers,machines,and so on. These electrical and electronic loads require various forms of power at different ranges and with different characteristics. So, for this reason the power is converted into the required forms (with desired qualities) by using some power electronic converters or power converters.
