Power Electronics
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 modern systems the conversion is performed with semiconductor switching devices such as diodes, thyristors and transistors, pioneered by R. D. Middlebrook and others beginning in the 1950s. In contrast to electronic systems concerned with transmission and processing of signals and data, in power electronics substantial amounts of electrical energy are processed. An AC/DC converter (rectifier) is the most typical power electronics device found in many consumer electronic devices, e.g. television sets, personal computers, battery chargers, etc. 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.
Transformers and Generators
A transformer is a passive electrical device that transfers electrical energy between two or more circuits. A varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force across a second coil wound around the same core. Electrical energy can be transferred between the two coils, without a metallic connection between the two circuits. Faraday's law of induction discovered in 1831 described the induced voltage effect in any coil due to changing magnetic flux encircled by the coil.
Digital System Design
Digital system design is process of designing or developing systems which represent information using a binary system It's easier to store, reproduce, transmit & manipulate digital data & cheaper/easier to design such systems. Microcontrollers, Microprocessors, Memory chips, FPGA are examples of digal ic design. Systems like for example a PC can be built using these components and that forms a digital system or platform.
Electric Circuit Analysis
In an electrical circuit the process of studying and analyzing the various electrical quantities involved, especially the nodal voltages and currents through calculations, is known as circuit analysis.
Transmission and Distribution
Transmission and distribution refers to the different stages of carrying electricity over poles and wires from generators to a home or a business. The primary distinction between the two is the voltage level at which electricity moves in each stage. After electricity has been generated, a system of electrical wires carries the electricity from the source of generation to our homes and businesses. These lines can be found overhead or sometimes in the ground, and, combined, transmission and distribution lines make up what is commonly called “the grid.” Transmission and distribution are two separate stages or systems on the grid.
ElectroMotive Force
Electromotive force, abbreviated emf (denoted {\displaystyle {\mathcal {E}}} {\mathcal {E}} and measured in volts),[1] is the electrical action produced by a non-electrical source.[2] A device that converts other forms of energy into electrical energy (a "transducer"),[3] such as a battery (converting chemical energy) or generator (converting mechanical energy),[2] provides an emf as its output.[3] Sometimes an analogy to water "pressure" is used to describe electromotive force.[4] (The word "force" in this case is not used to mean force of interaction between bodies, as may be measured in pounds or newtons.)
OPAMs and LINEAR ICs
A linear integrated circuit (linear IC) is a solid-state analog device characterized by a theoretically infinite number of possible operating states. It operates over a continuous range of input levels. In contrast, a digital IC has a finite number of discrete input and output states.
Management and Entrepreneurship(EEE)
An Entrepreneurial Management major or minor is for the person interested in organizing, owning, managing and assuming the risks of a business (entrepreneurship), or assisting organizations in developing new business opportunities (intrapreneurship). Curriculum is designed to range from introductory fundamentals through the development and implementation of real business opportunities.
Microcontroller and Microprocessor(EEE)
Microprocessor is an IC which has only the CPU inside it, i.e. only the processing powers such as Intel’s Pentium 1,2,3,4, core 2 duo, i3, i5 etc. These microprocessors don’t have RAM, ROM, and other peripheral on the chip. A system designer has to add them externally to make them functional. Applications of microprocessors includes Desktop PC’s, Laptops, notepads etc. But this is not the case with Microcontrollers. Microcontroller has a CPU, in addition with a fixed amount of RAM, ROM and other peripherals all embedded on a single chip. At times it is also termed as a mini computer or a computer on a single chip. Today different manufacturers produce microcontrollers with a wide range of features available in different versions. Some manufacturers are ATMEL, Microchip, TI, Freescale, Philips, Motorola etc.

Electrification(EEE)
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. The broad meaning of the term, such as in the history of technology, economic history, and economic development, usually applies to a region or national economy. Broadly speaking, electrification was the build-out of the electricity generation and electric power distribution systems that occurred in Britain, the United States, and other now-developed countries from the mid-1880s until around 1950 and is still in progress in rural areas in some developing countries. This included the transition in manufacturing from line shaft and belt drive using steam engines and water power to electric motors
