VOLTAGE REGULATOR FOR ELECTRONICS AND ELECTRICAL USE

Voltage Regulator Basic Definition 
A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level. A voltage regulator may be a simple "feed-forward" design or may include negative feedback control loops. It may use an electro-mechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages..continue..


voltage regulator,  any electrical or electronic device that maintains the voltage of a power source within acceptable limits. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage. Such a device is widely used in motor vehicles of all types to match the output voltage of the generator to the electrical load and to the charging requirements of the battery. Voltage regulators also are used in electronic equipment in which excessive variations in voltage would be detrimental...continue..


The automatic voltage regulator or AVR, as the name implies, is a device intended to regulate voltage automatically: that is to take a varying voltage level and turn it into a constant voltage level.
There is tremendous diversity in the size and type of devices that could qualify to be called an automatic voltage regulator. To get a sense of the degree of diversity among AVRs, consider an analogy about the term “spotlight” which can mean pixel-sized all solid state elements found in display devices to truck-mounted, power guzzlers to illuminate the night sky..continue..


The objective of this thesis is to design and develop a digital control system to maintain or control the terminal voltage for the laboratory's three phase synchronous machine..continue..


The 7805 IC or 5V regulator has a maximum current of 1.5A.  By adding transistor and resistor, you can increase its current capacity. The circuit below can deliver a current up to 5A at a regulated 5V supply, with just minimal modification...continue..

FRUITS AS BATTERY AND SOURCE OF ELECTRICITY

Electric Fruits Project   The purpose of this project was to find out which fruit would generate enough electricity to light a light bulb and to discover which fruit would light the bulb the longest. To conduct my experiments I used a Multimeter, copper and zinc wires & electrodes, alligator clips with leads, various light bulbs and five types of fruits. continue.. Why Do Citrus Fruits Produce Electricity?   In order to generate electricity, there must be a power source and a complete circuit. When using a citrus fruit to create electricity, these rules still apply. In a simple experiment using a citrus fruit, the components of the circuit include: a lemon or other fruit, wire, two different metal elements and a small light bulb. The lemon in this circuit serves as the battery and power source. continue.. Fruit Power Project   Purpose To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or li...

POWER SYSTEMS LOSS.COM: LOSSES IN ELECTRICAL SYSTEM

What is powersystemsloss all about?    System's loss reduction is now one of the most growing trends in every electric distribution utility. Primarily triggered by economics and regulation concerns, Transmission and Distribution companies now sets more focus in reducing losses and become as an efficient utility as possible in delivering power. Information found in this site will be very useful not only to electrical practitioners but it is also our goal to help students better understand the actual world. Thank you and lets all enjoy learning! continue..   Back to basic    n case you don't know, the power we get from our household electrical outlet didn't just appear in the thin air. It may appear that it is coming out from our walls but we all know that looks can be deceiving. Before reaching our respective homes, electric current passes through miles and miles of c...

INDUCTION COOKER:PRINCIPLES OF OPERATION

What is Induction Cooking?   Induction cooking uses induction heating to directly heat a cooking vessel, as opposed to using heat transfer from electrical coils or burning gas as with a traditional cooking stove. To be used on an induction cooktop, a cooking vessel must be made of a ferromagnetic metal, or placed on an interface disk which enables non-induction cookware to be used on induction surface. In an induction cooker, a coil of copper wire is placed underneath the cooking pot. An alternating electric current flows through the coil, which produces an oscillating magnetic field. This field induces an electric current in the pot. Current flowing in the metal pot produces resistive heating which heats the food. While the current is large, it is produced by a low voltage. continue.. Advantage and Disadvantages of Induction Cooker   To serious cooks, the most important favorable point about induction cookers--given that they are as or more "powerful" at heating...
