This book presents physics-based electro-thermal models of bipolar power semiconductor devices including their packages, and describes their implementation in MATLAB and Simulink. It is a continuation of our first book Modeling of Bipolar Power Semiconductor Devices. The device electrical models are developed by subdividing the devices into different regions and the operations in each region, along with the interactions at the interfaces, are analyzed using the basic semiconductor physics equations that govern device behavior. The Fourier series solution is used to solve the ambipolar diffusion equation in the lightly doped drift region of the devices. In addition to the external electrical characteristics, internal physical and electrical information, such as junction voltages and carrier distribution in different regions of the device, can be obtained using the models. The instantaneous dissipated power, calculated using the electrical device models, serves as input to the thermal model (RC network with constant and nonconstant thermal resistance and thermal heat capacity, or Fourier thermal model) of the entire module or package, which computes the junction temperature of the device. Once an updated junction temperature is calculated, the temperature-dependent semiconductor material parameters are re-calculated and used with the device electrical model in the next time-step of the simulation. The physics-based electro-thermal models can be used for optimizing device and package design and also for validating extracted parameters of the devices. The thermal model can be used alone for monitoring the junction temperature of a power semiconductor device, and the resulting simulation results used as an indicator of the health and reliability of the semiconductor power device.

Worldwide, the effects of environmental, economic, social, political, and technical factors have led to the rapid deployment of various sources of renewable energy-based power generation. The incorporation of these generation technologies has led to the development of a broad array of new methods and tools to integrate this new form of generation into the power system networks. This book, comprises into five modules gives a comprehensive discussion on various renewable energy-based distributed generation (DG) technologies Module 1 discuss about the need for the distributed generation, Module 2 detailed description about the Distribution Generation Resources, Module 3 concern with the economic and control aspect of DG’s, Module 4 Proposes to Introduction to electrical distribution system and finally in Module 5 ends with the classification and design features of distribution system

This book uses a multi-method approach to explain why recent Iowa governors have been able to stay in office significantly longer than their peers. Voters in Iowa value a personal connection with their governor and those governors who ignore that expectation are held accountable at the polls.

This SpringerBrief focuses on modeling and power evaluation of high-speed craft. The various power prediction methods, a principal design objective for high-speed craft of displacement, semi-displacement, and planing type, are addressed. At the core of the power prediction methods are mathematical models for resistance and propulsion efficiency. The models are based on the experimental data of various high-speed hull and propeller series. The regression analysis and artificial neural network (ANN) methods are used as an extraction tool for this kind of mathematical models. A variety of mathematical models of this type are discussed in the book. Once these mathematical models have been developed and validated, they can be readily programmed into software tools, thereby enabling the parametric analyses required for the optimization of a high-speed craft design. This book provides the foundational reference for these software tools, and their use in the design of high-speed craft. High-speed craft are very different from conventional ships. Current professional literature leaves a gap in the documentation of best design practices for high-speed craft. This book is aimed at naval architects who design and develop various types of high-speed vessels.

How leaders can achieve something meaningful—transform a brand, a workplace, a technology, themselves—beyond holding an influential position. Do you want to do work that is worthy of your time and talent? Do you want to make your mark on your industry, company, or within your community? Are you satisfied with the fact that reengineering, quality improvements, and other changes never really make a lasting impact? Then you need to go beyond the techniques of improvement and learn the skills that it takes to be extraordinary. The power to be extraordinary is not one we are born with. Rather, it is a power that one can learn, and Tracy Goss helps executives realize this power. Here in this book for the first time, Goss makes her coursework available to the general reader. Goss’s unique methodology shows how you how you can “put at risk the success you’ve become for the power of making the impossible happen.” She positions executives to take on the future that they dream about. She teaches how to behave differently so that you are free of past constraints. She shows how you can be at home in the environment in which you are constantly surrounded by threats, and how to transcend the ordinary to make the impossible happen. Her work has resulted in many important life changes and organizational reinventions worldwide. “Goss offers powerful information, far above the glib self-help mush that already lines the shelves. She answers the fundamental question of why management fads do not work: the personal work has not yet been done.” —Library Journal
