We know that all the electrical and electronic appliances run on electricity. The home appliances are like air conditioners, refrigerators, televisions, greasers, washing machines, grinders, etc. Have you ever noticed that why the plug systems on the wall contain three pins instead of two pins? Home appliances are designed with metals, metal components, and metal frames. Metals are great conductors that allow the flow of current through it. But there is a … [Read more...]
Induction Heating Working & Its Applications
The fundamental induction heating principle was introduced and applied in manufacturing industries in 1920. During the Second World War, the development of technology has been increased to reach urgent requirements of a period of war for a quick, consistent procedure to solidify the parts of the metal engines. At present, technology is focusing on lean industrialized methods & giving importance to improved quality control of induction technology. This … [Read more...]
Maximum Power Transfer Theorem – Examples and Applications
In any electrical system, the highest amount of power is used to transmit the power to the load for its operation. the best example of this is an audio amplifier as they transmit the maximum amount of current from the amplifier to the speaker. Similarly, in radio system, the highest amount of current is supplied from the power amplifier to the antenna. For this, the value of load resistance should be ideal for supplying the highest amount of current toward … [Read more...]
Overvoltage and Under Voltage Protection System
If any unexpected fluctuation in the power supply may cause many problems in the industries, homes, offices. Voltage fluctuations in the electric power supply have a very poor effect on connected load. These fluctuations of over voltage and under voltage protection system are produced by many reasons which are like voltage surges, limiting, overload and etc. General applications of these systems are used in agriculture motors, water pumps and etc. In this … [Read more...]
Basics of 555 Timer IC and Working Principle
In the year 1971 by Hans R. Camenzind has designed the 555 timer integrated circuit with the contract of Signetics. Later on it came to Dutch company which is Philips semiconductors. The manufacturing of 555 timer IC includes the transistors, diodes, and resistors on the silicon chip which are on the 8 – pin mini dual in line packages. There are different types of timers available like 556 which include the 14 pin dual in line package are gathering the … [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...]
