Nuclear battery (1)
Nuclear batteries offer a compact, lightweight, and self-contained power source that can last for decades without needing replacement like chemical batteries. They generate electricity through the emissions from radioactive isotopes without relying on nuclear reactions, avoiding radioactive waste. Betavoltaics uses the energy from beta particles emitted by a radioactive gas to generate electron-hole pairs in silicon, producing an electric current. Direct charging generators sustain oscillations in an LC circuit through energy absorbed from alpha particles decaying in the circuit's core, delivering excess energy to a load. While nuclear batteries have applications in space, medical devices, mobile electronics, and sensors, their high initial cost and need to meet radiation safety standards must first be addressed.

Nuclearbattery
Nuclear batteries use the incredible amount of energy released naturally by tiny bits of radio active material without any fission or fusion taking place inside the battery. These devices use thin radioactive films that pack in energy at densities thousands of times greater than those of lithium-ion batteries. Because of the high energy density nuclear batteries are extremely small in size. Considering the small size and shape of the battery the scientists who developed that battery fancifully call it as "DAINTIEST DYNAMO". The word 'dainty' means pretty.

Nuclearbattery 160307125636
Nuclear batteries are devices that use energy from the decay of radioactive isotopes to generate electricity. They have no nuclear chain reaction and produce no radioactive waste. The technology began in 1913 and was further developed in the 1950s for uses in small electronics. There are three main types: thermionic converters, radioisotope thermoelectric generators, and betavoltaic cells. Betavoltaic cells directly convert the ionization of electrons from beta particle emission into electricity using a semiconductor. Nuclear batteries have advantages of being reliable, compact, and long-lasting power sources, but also have high costs and safety risks. They have applications in space, automobiles, medicine, and underwater devices.

NECULAR BATTERIES
Nuclear batteries generate electricity through the emissions of radioactive isotopes and have a lifespan of decades without needing replacement like chemical batteries. They work by introducing a radioactive source into a PN-junction semiconductor, where beta particle collisions create a Fermi potential that allows the movement of electrons from one electrode to a load and back. Nuclear batteries have merits like a long life, reliability, efficiency and use of nuclear waste as fuel, but also have high costs, less advanced energy conversion, and regulatory issues around radioactive materials. They can be used in space applications, medical devices, and mobile or automobile applications where long-lasting power is needed.
Organic Solar cell
The document discusses organic solar cells, which use organic electronics to produce electricity from sunlight. Organic solar cells work by absorbing light to generate excitons, dissociating the excitons into free charges at donor-acceptor interfaces, and transporting the charges through organic semiconductors. The document outlines the basic principles of light absorption, exciton diffusion, exciton dissociation, and charge transport in organic solar cells. It also describes how organic solar cells are characterized by parameters such as power conversion efficiency, open circuit voltage, short circuit current, and fill factor.
Solar cell
Solar cells convert sunlight into electrical energy using semiconducting materials like silicon. They are made from either monocrystalline or polycrystalline silicon. Monocrystalline solar cells are more efficient because they are made of pure silicon crystals but are more expensive to produce. Polycrsytalline solar cells contain multiple silicon crystals mixed with other materials, making them less efficient but cheaper to manufacture. Solar cells use the photovoltaic effect where light absorption generates voltage across the PN junction of the semiconductor material.
Solar Cell : Working Principle
Solar cells convert sunlight directly into electrical power through the photovoltaic effect. They have several advantages such as being clean, renewable, and producing no pollution or greenhouse gases. Solar cells work by using semiconducting materials, usually silicon, to create a p-n junction. When sunlight hits the junction, electrons are knocked loose, creating an electrical current.
MultiJunctionSolarCells (1)
Multi-junction solar cells use multiple semiconductor materials with different bandgaps stacked together to absorb a wider range of the solar spectrum and achieve higher efficiencies than single-material solar cells. They are fabricated using techniques like metalorganic vapor phase epitaxy and molecular beam epitaxy to precisely control the growth of each layer for optimal bandgap and lattice matching. Current multi-junction cells can achieve efficiencies over 40% and are used in space applications, though high costs have limited terrestrial use primarily to concentrated photovoltaics. Further efficiency improvements may come from new materials like quantum dots, optimizing existing layer designs, and increasing the number of junctions to finer divide the solar spectrum.
flexible solar panel
The document discusses flexible organic solar cells. It outlines their construction, which involves depositing an electron donor and acceptor layer on a flexible material using chemical vapor deposition. It explains how these solar cells work by absorbing light which promotes electrons in the donor layer to the LUMO level, allowing them to be transferred to the acceptor layer and collected at electrodes. Flexible organic solar cells are advantageous because they can be made thin, lightweight and flexible on materials like plastic or paper, making them portable and low-cost to manufacture using vapor deposition. The conclusion states that flexible organic solar cells have greater efficiency and performance than traditional rigid solar panels due to their physical structure.
Hybrid Emergency
This document discusses methods for modeling and controlling voltage collapse in electrical power systems. It describes decomposing large-scale power system models into continuous and discrete components. The document also presents an approach using model predictive control to implement emergency voltage control through optimal coordination of automatic voltage regulators and transformer tap changers.
Seminar
Electromagnetic induction is the process of generating an electric current from a magnetic field. Michael Faraday discovered induction in 1831 through experiments showing that a current was induced in a coil of wire when a magnet was moved in and out of the coil. The magnitude of the induced current depends on factors like the strength of the magnetic field, the speed and direction of motion, and the number of turns in the coil. This principle is applied in electric generators to produce electricity.
Power quality issues & solutions in electrical system-felidae systems
Power quality refers to how well an electrical system delivers power to devices without loss of performance. Poor power quality can cause devices to malfunction or fail prematurely. Harmonics from nonlinear loads are a major cause of power quality issues, distorting the voltage waveform and increasing electrical losses. This can lead to premature equipment failure or require oversizing equipment. Various techniques can be used to suppress harmonic distortion and improve power quality for utilities and users.
Seminar on stepper motor
This document provides an introduction to DC motors and stepper motors. It discusses the basic components and workings of brushed DC motors, which were one of the earliest electric motor designs due to their simple and easy to control nature. It then describes stepper motors, which differ from DC motors in that their commutation is controlled externally rather than with a commutator. Key aspects of stepper motors covered include their voltage rating, resistance-per-winding, degrees per step, and unipolar and bipolar configurations. The document concludes by discussing how to identify the wires of a stepper motor and provides a basic program for controlling a stepper motor by firing the signal wires in sequence.

—Injection of the wind power into an electric grid affects the power quality. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed according to the guideline specified in International Electro-technical Commission standard, IEC-61400. The influence of the wind turbine in the grid system concerning the power quality measurements are-the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operation and these are measured according to national/international guidelines. The paper study demonstrates the power quality problem due to installation of wind turbinewith the grid. In thisproposed scheme STATic COMpensator (STATCOM) is connected at a point of common coupling with a battery energy storage system (BESS) to mitigate the power quality issues. The battery energy storage is integrated to sustain the real power source under fluctuating wind power. The STATCOM control scheme for the grid connected wind energy generation system for power quality improvement is simulated using MATLAB/SIMULINK in power system block set. The effectiveness of the proposed scheme relives the main supply source from the reactivepower demand of the load and the induction generator. The development of the grid co-ordination rule and the scheme for improvement in power quality norms as per IEC-standard on the grid has been presented

automatic power factor controller
This document discusses power factor correction and automatic power factor correction (APFC) systems. It explains that power factor is the ratio of active power to apparent power and can be lagging or leading. Low power factors are caused by inductive loads and non-linear loads. APFC systems use capacitors in automatic steps controlled by a microprocessor to maintain a high power factor under varying loads without manual intervention or risk of overvoltage. This improves efficiency and reduces utility penalties and equipment loading and sizes. The document provides specifications for capacitor selection and switching equipment for APFC systems.
MOCT
The document describes a Magneto Optic Current Transducer (MOCT) which uses the Faraday effect to measure electric current. It consists of an optical sensor near the current carrying conductor, fiber optic cables, and a signal processing unit. The sensor contains polarized light which rotates proportionally to the current. This rotation is measured and transmitted via fiber optics to the processing unit. Key advantages over conventional transformers include increased safety, simpler insulation, and immunity to electromagnetic interference. While MOCTs provide benefits, their accuracy is currently insufficient for power system applications.
Transformer testing
The document describes how to conduct short circuit and open circuit tests on transformers using a DPATT-3Bi device to measure copper and iron losses, respectively. It provides details on the test setups, calculations for full load current and no load current, and how to interpret the results displayed on the DPATT-3Bi screen. The document also lists standard limits for transformer impedance voltages and losses according to Indian standards.
Power quality
This document discusses power quality issues such as voltage sags, interruptions, spikes, swells, and harmonics. It explains the causes and consequences of each issue. Solutions discussed include improving the electric grid, using distributed energy resources like generators and energy storage, following standards, installing enhanced interface devices, and making equipment less sensitive. The key is preventing power quality problems through various measures to avoid losses.
Reactive power compensation
This document presents an overview of reactive power compensation. It defines reactive power compensation as managing reactive power to improve AC system performance. There are two main aspects: load compensation to increase power factor and voltage regulation, and voltage support to decrease voltage fluctuations. Several methods of reactive power compensation are discussed, including shunt compensation using capacitors and reactors, series compensation, static VAR compensators (SVCs), static compensators (STATCOMs), and synchronous condensers. SVC and STATCOM technologies are compared, with STATCOMs having advantages of smaller components, better control, and transient response.
Stepper motor
A stepper motor converts electrical pulses into discrete mechanical movements of its shaft. The shaft rotates in discrete step increments that correspond directly to the sequence and frequency of input pulses. There are three main types of stepper motors: variable-reluctance, permanent magnet, and hybrid. Stepper motors provide controlled movement and are well-suited for applications that require control of rotation angle, speed, position, and synchronization. They have advantages like full torque at standstill and excellent response to starting, stopping, and reversing.
