Book Description
DESIGN OF THREE-PHASE AC POWER ELECTRONICS CONVERTERS Comprehensive resource on design of power electronics converters for three-phase AC applications Design of Three-phase AC Power Electronics Converters contains a systematic discussion of the three-phase AC converter design considering various electrical, thermal, and mechanical subsystems and functions. Focusing on establishing converter components and subsystems models needed for the design, the text demonstrates example designs for these subsystems and for the whole three-phase AC converters considering interactions among subsystems. The design methods apply to different applications and topologies. The text presents the basics of the three-phase AC converter, its design, and the goal and organization of the book, focusing on the characteristics and models important to the converter design for components commonly used in three-phase AC converters. The authors present the design of subsystems, including passive rectifiers, inverters and active rectifiers, electromagnetic interference (EMI) filters, thermal management system, control and auxiliaries, mechanical system, and application considerations, and discuss design optimization, which presents methodology to achieve optimal design results for three-phase AC converters. Specific sample topics covered in Design of Three-phase AC Power Electronics Converters include: Models and characteristics for devices most commonly used in three-phase converters, including conventional Si devices, and emerging SiC and GaN devices Models and selection of various capacitors; characteristics and design of magnetics using different types of magnetic cores, with a focus on inductors Optimal three-phase AC converter design including design and selection of devices, AC line inductors, DC bus capacitors, EMI filters, heatsinks, and control. The design considers both steady-state and transient conditions Load and source impact converter design, such as motors and grid condition impacts For researchers and graduate students in power electronics, along with practicing engineers working in the area of three-phase AC converters, Design of Three-phase AC Power Electronics Converters serves as an essential resource for the subject and may be used as a textbook or industry reference.

Book Description
This book is a compilation of knowledge about computer models in the three-phase stator reference frame. Chapters explore several aspects of the topic and build upon research previously presented by contributors. The book aims to provide interesting solutions to problems encountered in the design of railway and analysis in railway motors. The modeling approaches proposed by the authors in this book may become an incentive for readers and researchers to develop their ‘lifehacks’ to solve new problems in induction motor design and testing. Key topics presented in the book: - Approximate calculations of induction motor equivalent T-shaped circuit parameters with the use of catalogue data - Simulations of different types of shaft load, including fluid coupling - Receiving static characteristics of an electric machine during simulation by means of dynamic model - Simulation of the electric drive’s specific applications with three-phase induction motors building - Direct start of an induction motor as part of an auxiliary drive of an AC electric locomotive, containing a capacitor phase splitter, starting with different types of shaft loads (fan or compressor). Special attention has been given to the description of the thermal model of an induction motor with a squirrel-cage rotor, which makes it possible to simulate operating modes when powered by an unbalanced voltage, as well as with squirrel cage defects. The thermal model is presented as a detailed superstructure to the model of electromechanical processes of an induction electric machine. Other key features of the book include references for further reading, an appendix for the parameters of the equivalent thermal circuit of an NVA-55 induction motor. The material presented in the book is of interest to railway motor engineers, specialists in electromechanics and electric drives who use SPICE-compatible CAD applications in their work.

Book Description
In developing economies such as India, improving the efficiency of home appliances is of high priority in locations which are characterized by a weak electric distribution system. Ceiling fans are one of the most used home appliances in India. They typically operate for many hours, and since most of them are driven by inefficient, low cost single phase induction motors, the total power loss is nontrivial. To overcome the inefficiency of single phase induction motors, brushless dc motors have been increasingly used in ceiling fans to achieve high efficiency and power factor at multiple speed settings. However, they are more expensive than conventional ceiling fan motors due to the additional cost of permanent magnets and power electronic drive circuit. Three phase in contrast to single phase induction motors have proven to have a superior performance especially for high power applications. From a manufacturing point of view, they are no more expensive to build than single phase induction motors. Also, three phase induction motors require no permanent magnets, which makes them economically attractive. To be able to use three phase induction motors in home appliances at variable speed, a power electronic drive is required to convert the single phase supply to three phase. The drive circuit can also be controlled to improve the input power factor. With the advancement of power electronic technology and integrated control devices, such motor drives can be made efficient and cost effective. This thesis explores the design and optimization of three phase squirrel cage induction motors for the application of ceiling fans in India, with the objective of achieving a balance between efficiency and cost. A detailed analytical model for a low speed, low power three phase squirrel cage induction motor is developed. The analytical model is validated using finite-element analysis. This thesis also optimizes the motor design using genetic algorithms. The optimized design weighs 4.5kg and achieves 70% efficiency, which proves more efficient than existing ceiling fan motors in India. The optimized design is also validated in finite-element analysis. Finally, this thesis presents a simulation study of the motor drive implementation for the proposed three phase induction motor.
