Power electronics

Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter. Electronics has had a major effect on the development of modern society. The identification of the electron in , along with the subsequent invention of the vacuum tube which could amplify and rectify small electrical signals, inaugurated the field of electronics and the electron age. Until , this field was called "radio technology" because its principal application was the design and theory of radio transmitters , receivers , and vacuum tubes.

The term " solid-state electronics " emerged after the first working transistor was invented by William Shockley , Walter Houser Brattain and John Bardeen at Bell Labs in The MOSFET was the first truly compact transistor that could be miniaturised and mass-produced for a wide range of uses, revolutionizing the electronics industry , and playing a central role in the microelectronics revolution and Digital Revolution.

The MOSFET has since become the basic element in most modern electronic equipment, and is the most widely used electronic device in the world. Electronics is widely used in information processing , telecommunication , and signal processing. The ability of electronic devices to act as switches makes digital information-processing possible.

Interconnection technologies such as circuit boards , electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed electronic components into a regular working system , called an electronic system ; examples are computers or control systems.

An electronic system may be a component of another engineered system or a standalone device. As of [update] most electronic devices [3] use semiconductor components to perform electron control.

Commonly, electronic devices contain circuitry consisting of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes , integrated circuits , optoelectronics , and sensors , associated passive electrical components , and interconnection technologies.

The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible. The study of semiconductor devices and related technology is considered a branch of solid-state physics , whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering.

This article focuses on engineering aspects of electronics. An electronic component is any physical entity in an electronic system used to affect the electrons or their associated fields in a manner consistent with the intended function of the electronic system. Components are generally intended to be connected together, usually by being soldered to a printed circuit board PCB , to create an electronic circuit with a particular function for example an amplifier , radio receiver , or oscillator.

Components may be packaged singly, or in more complex groups as integrated circuits. Some common electronic components are capacitors , inductors , resistors , diodes , transistors , etc. Components are often categorized as active e. Vacuum tubes Thermionic valves were among the earliest electronic components.

They played a leading role in the field of microwave and high power transmission as well as television receivers until the middle of the s. Vacuum tubes are still used in some specialist applications such as high power RF amplifiers , cathode ray tubes , specialist audio equipment, guitar amplifiers and some microwave devices.

Thomas J. Watson Jr. From that time on transistors were almost exclusively used for computer logic and peripherals. However, early junction transistors were relatively bulky devices that were difficult to manufacture on a mass-production basis, which limited them to a number of specialised applications. Circuits and components can be divided into two groups: analog and digital. A particular device may consist of circuitry that has one or the other or a mix of the two types.

An important electronic technique in both analog and digital electronics involves the use of feedback. Among many other things this allows very linear amplifiers to be made with high gain, and digital circuits such as registers, computers and oscillators. Most analog electronic appliances, such as radio receivers, are constructed from combinations of a few types of basic circuits. Analog circuits use a continuous range of voltage or current as opposed to discrete levels as in digital circuits.

The number of different analog circuits so far devised is huge, especially because a 'circuit' can be defined as anything from a single component, to systems containing thousands of components. Analog circuits are sometimes called linear circuits although many non-linear effects are used in analog circuits such as mixers, modulators, etc. Good examples of analog circuits include vacuum tube and transistor amplifiers, operational amplifiers and oscillators.

One rarely finds modern circuits that are entirely analog. These days analog circuitry may use digital or even microprocessor techniques to improve performance.

This type of circuit is usually called "mixed signal" rather than analog or digital. Sometimes it may be difficult to differentiate between analog and digital circuits as they have elements of both linear and non-linear operation.

An example is the comparator which takes in a continuous range of voltage but only outputs one of two levels as in a digital circuit. Similarly, an overdriven transistor amplifier can take on the characteristics of a controlled switch having essentially two levels of output. Digital circuits are electric circuits based on a number of discrete voltage levels.

Digital circuits are the most common physical representation of Boolean algebra , and are the basis of all digital computers.

To most engineers, the terms "digital circuit", "digital system" and "logic" are interchangeable in the context of digital circuits. Most digital circuits use a binary system with two voltage levels labeled "0" and "1". Often logic "0" will be a lower voltage and referred to as "Low" while logic "1" is referred to as "High".

However, some systems use the reverse definition "0" is "High" or are current based. Quite often the logic designer may reverse these definitions from one circuit to the next as he sees fit to facilitate his design. The definition of the levels as "0" or "1" is arbitrary. Ternary with three states logic has been studied, and some prototype computers made. Computers , electronic clocks , and programmable logic controllers used to control industrial processes are constructed of digital circuits.

Digital signal processors are another example. Heat generated by electronic circuitry must be dissipated to prevent immediate failure and improve long term reliability. Means to achieve greater dissipation include heat sinks and fans for air cooling, and other forms of computer cooling such as water cooling.

These techniques use convection , conduction , and radiation of heat energy. Electronic noise is defined [32] as unwanted disturbances superposed on a useful signal that tend to obscure its information content.

Noise is not the same as signal distortion caused by a circuit. Noise is associated with all electronic circuits. Noise may be electromagnetically or thermally generated, which can be decreased by lowering the operating temperature of the circuit. Other types of noise, such as shot noise cannot be removed as they are due to limitations in physical properties. Mathematical methods are integral to the study of electronics.

To become proficient in electronics it is also necessary to become proficient in the mathematics of circuit analysis. Circuit analysis is the study of methods of solving generally linear systems for unknown variables such as the voltage at a certain node or the current through a certain branch of a network.

Also important to electronics is the study and understanding of electromagnetic field theory. Due to the complex nature of electronics theory, laboratory experimentation is an important part of the development of electronic devices. These experiments are used to test or verify the engineer's design and detect errors. Historically, electronics labs have consisted of electronics devices and equipment located in a physical space, although in more recent years the trend has been towards electronics lab simulation software, such as CircuitLogix , Multisim , and PSpice.

Today's electronics engineers have the ability to design circuits using premanufactured building blocks such as power supplies , semiconductors i. Electronic design automation software programs include schematic capture programs and printed circuit board design programs.

Many different methods of connecting components have been used over the years. For instance, early electronics often used point to point wiring with components attached to wooden breadboards to construct circuits. Cordwood construction and wire wrap were other methods used.

Electronic systems design deals with the multi-disciplinary design issues of complex electronic devices and systems, such as mobile phones and computers. The subject covers a broad spectrum, from the design and development of an electronic system new product development to assuring its proper function, service life and disposal.

Power electronics is the application of solid-state electronics to the control and conversion of electric power. The first high power electronic devices were mercury-arc valves. In contrast to electronic systems concerned with transmission and processing of signals and data, in power electronics substantial amounts of electrical energy are processed. The power range is typically from tens of watts to several hundred watts. In industry a common application is the variable speed drive VSD that is used to control an induction motor. The power range of VSDs start from a few hundred watts and end at tens of megawatts. The power conversion systems can be classified according to the type of the input and output power.
