There are various types of power electronic converters which are frequently used in electric power system applications such as power converter, regulated power supply, DC power supply and so on. The power electronics converters can be classified as AC to DC converter or Rectifier, DC to AC converter or Inverter, AC to AC converter, DC to DC converter, and so on. These converters are again classified into different types based on different criteria. If we … [Read more...]

Steps to Convert AC to DC – Converter & Circuit
Electrical power supply became as a basic need in our day-to-day life, the power we are availing is 230V 50Hz AC supply. But, by using power electronics converter circuits this power can be converted into the required form and range. These converters are power electronics circuits which are further classified as step-down & step-up converters, voltage stabilizer circuit, AC to DC, DC to DC, DC to AC converter circuits and so on. Most of the … [Read more...]
Different Types of Inductor and Its Applications
There are various types of inductors are available in the market based on its ratings and sizes and ratings. Their physical sizes differ from small sizes to the enormous transformer, based on the AC frequency being used and power being handled. An Inductor is one of the basic electrical components used in much wider application areas namely signal controlling, voltage stabilization, noise elimination, automobile operations, power electronic equipment, etc. … [Read more...]
Thermistor Working Procedure with Applications
A thermistor is a temperature sensor constructed of semiconductor material that exhibits a large modification in resistance in proportion to a tiny low modification in temperature. Thermistors are inexpensive, rugged, reliable and responds quickly. Because of these qualities thermistors are used to measure simple temperature measurements, but not for high temperatures. Thermistor is easy to use, cheap, durable and respond predictably to a change in … [Read more...]
Power MOSFET Basics, Working Principle and Applications
The Power MOSFET is a type of MOSFET. The operating principle of power MOSFET is similar to the general MOSFET. The power MOSFETS are very special to handle the high level of powers. It shows the high switching speed and by comparing with the normal MOSFET, the power MOSFET will work better. The power MOSFETs is widely used in the n-channel enhancement mode, p-channel enhancement mode, and in the nature of n-channel depletion mode. Here we have explained … [Read more...]
Wireless Power Transmission Technology with Applications
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...]
Know about Different Types of Lights in Lighting System
In the 19th century, the first practical incandescent lamp was invented by Thomas Edison and Joseph Swan. Since then there has been significant improvements in different types of bulbs and their efficiencies. There are different types of lights or lamps around, and they all being designed with a conceived image in mind. Major types of lamps or bulbs are commonly found in the lighting systems of homes, offices, factories, electrical devices etc. The … [Read more...]
What is a Steam Boiler? Working, Types & Applications
Generally, Power plants require steam for the purpose of heating. Hence, this purpose is fulfilled by the boiler, where the steam is produced by boiling water. Basically, the steam is produced by boiling water beyond its boiling point where it changes its state from liquid to vapor and this vapor is known as steam. So, for the production of steam, we require water and steam. To produce steam we need a boiler where available water is heated by means of some … [Read more...]
Four Point Starter Working and Applications
A device that gives the motor some initiation to start safely is termed as a Starter. While starting a motor, it draws huge current from the line which damages the internal parts of the motor. Four-point starter helps in limiting the starting current such that the motor begins to attain speed slowly and runs smoothly. It is just similar to a three-point starter. The basic difference is, in the four-point starter field weakening speed control is possible by … [Read more...]
Three Point Starter – Construction, Working, Drawbacks and Applications
A device that gives the motor some initiation to start safely is known as Starter. Similarly, the three-point starter is common for the starting purpose which is used to start DC compound or shunt motors. While starting DC shunt motor it draws huge current from the line which damages the internal parts of the motor. So, a three-point starter helps in limiting the starting current such that the motor begins to attain speed slowly and runs smoothly. … [Read more...]
