The induction machine, invented by Nikola Tesla in 1888, has become widely used for electromechanical energy conversion due to its ease of manufacture and robustness. It is available in power ratings from fractional horsepower to megawatts. As an AC electromechanical energy conversion device, the induction machine interfaces with the external world through both a mechanical rotating shaft port and an electrical terminal port to connect to a three-phase AC supply. This module will discuss the common three-phase induction machine.

Electric motors and generators operate based on the principles of electromagnetic induction. Motors convert electrical energy to mechanical motion, while generators convert mechanical motion to electrical energy. They both work by using magnetic fields to exert forces on electric currents or moving charges. The direction of these forces causes rotation, which is then harnessed to power other devices or generate electricity from mechanical inputs. Back-EMF is a reaction force that ensures conservation of energy during these conversions between electrical and mechanical domains. The efficiency of motors and generators depends on factors like resistance, friction, and how well the device's geometry maximizes the electromagnetic forces involved.

Hybrid inverter project report
The need of running AC Loads on solar energy leads us to the design of Solar Power Inverter.. Since the majority of modern conveniences all run on 220 volts AC, the Power Inverter will be the heart of the Solar Energy System. It not only converts the low voltage 12 volts DC to the 220 volts AC that runs most appliances, but also can charge the batteries if connected to the utility grid as in the case of a totally independent stand-alone solar power system. These are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger.
An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits. Solid-state inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power. Inverters are commonly used to supply AC power from DC sources such as solar panels or batteries.

A Three Phase Multi Level Converter for grid Connected PV System
Photovoltaic energy is a wide kind of green energy. A high performance on these systems is needed to make the most of energy produced by solar cells. Also, there must be a constant adaptation due to the continuous variation of power production. Control techniques for Power Converters like the MPPT algorithm (Maximum Power Point Tracking) present very good results on photovoltaic chains. Nevertheless, losses on power elements reduce global performance and the voltage/current adaptation is not always possible. This paper presents a single-phase 11-level (5 H-bridges) cascade multilevel DC- AC grid-tied inverter. Each inverter bridge is connected to a 200 W solar panel. OPAL-RT lab was used as the hardware in the loop (HIL) real-time control system platform where a Maximum Power Point Tracking (MPPT) algorithm was implemented based on the inverter output power to assure optimal operation of the inverter when connected to the power grid as well as a Phase Locked Loop (PLL) for phase and frequency match. A novel SPWM scheme is proposed in this paper to be used with the solar panels that can account for voltage profile fluctuations among the panels during the day. Simulation and experimental results are shown for voltage and current during synchronization mode and power transferring mode to validate the methodology for grid connection of renewable resources.

wireless electricity
This document summarizes wireless electricity and power transfer techniques. It discusses Nikola Tesla's early work transmitting power wirelessly and defines different wireless power transfer methods like inductive coupling and resonant inductive coupling. Inductive coupling uses electromagnetic induction to transfer power between devices in close proximity like wireless charging pads. Resonant inductive coupling combines induction with resonance to transfer power over greater mid-range distances. The document also describes transferring power over long distances using microwave transmission and proposes collecting solar power in space and transmitting it to receivers on the ground. While wireless power has advantages like efficiency and flexibility, its disadvantages include higher setup costs and potential interference issues depending on the transmission method used.

1) Torque is produced in an induction motor due to the interaction between the rotating stator flux and currents induced in the rotor coils.
2) As the stator flux rotates, it induces sinusoidally varying voltages in three rotor coils placed 120 degrees apart, causing currents to flow in the coils.
3) The currents in the rotor coils interact with the rotating stator flux to produce a torque that tends to rotate the rotor in the same direction as the stator flux.

Chapter 7 transformers
The document contains lecture notes about transformers. It discusses that a transformer transfers electrical energy from one voltage level to another without mechanical energy conversion. It has two circuits called primary and secondary linked by a magnetic circuit. An AC voltage applied to the primary induces a voltage in the secondary according to Faraday's law of induction. The core is made of laminated steel to reduce eddy current losses. Transformers can be of core type or shell type and are used to step up or step down voltages for applications like power distribution or electronics.

- 1. Electrical Machines II Prof. Krishna Vasudevan, Prof. G. Sridhara Rao, Prof. P. Sasidhara Rao Indian Institute of Technology Madras Induction Machines 1 Introduction The induction machine was invented by NIKOLA TESLA in 1888. Right from its incep- tion its ease of manufacture and its robustness have made it a very strong candidate for electromechanical energy conversion. It is available from fractional horsepower ratings to megawatt levels. It finds very wide usage in all various application areas. The induction machine is an AC electromechanical energy conversion device. The machine interfaces with the external world through two connections (ports) one mechanical and one electrical. The mechanical port is in the form of a rotating shaft and the electrical port is in the form of terminals where AC supply is connected. There are machines available to operate from three phase or single phase electrical input. In this module we will be discussing the three phase induction machine. Single phase machines are restricted to small power levels. 1
