Book Synopsis Transient Electro-Thermal Modeling on Power Semiconductor Devices by : Tanya Kirilova Gachovska
Download or read book Transient Electro-Thermal Modeling on Power Semiconductor Devices written by Tanya Kirilova Gachovska and published by Springer Nature. This book was released on 2022-06-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Research on Modern Power Semiconductor Modelling Methodology for Efficiency Evaluation of Power Electronic Systems in Electromagnetic Transient Simulation by : Yanming Xu
Download or read book Research on Modern Power Semiconductor Modelling Methodology for Efficiency Evaluation of Power Electronic Systems in Electromagnetic Transient Simulation written by Yanming Xu and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power electronics technology has rapidly developed during the past decades. Power electronics systems aim to achieve high efficiency as power conversion interfaces while fulfilling the performance and reliability requirements. The key to achieving these objectives is power semiconductors, which dictate the power electronics system's efficiency, power density, and reliability. In recent years, traditional Silicon (Si) devices are reaching their material limits. Meanwhile, new Wide-Bandgap (WBG) devices such as Silicon Carbide (SiC) and Gallium Nitride (GaN) devices have been commercialized, featuring high breakdown voltage, fast switching speed, and high thermal capability. On the other hand, semiconductor devices are typically exposed to repetitive heat pulses and are often the most critical components affecting system reliability. Consequently, a comprehensive modelling method for modern power semiconductors that can describe various devices' switching behaviors is highly desirable by power electronics engineers and manufacturers. This research focuses on developing a simulation-based modelling methodology for modern power semiconductors to evaluate the power electronics system's efficiency. A multi-level simulation strategy has been proposed and implemented in PSCAD/EMTDC. A generalized transient semiconductor model has been developed, which can reproduce the device's switching behaviors. Subsequently, the power losses are obtained to form a multi-dimensional power loss look-up table under a wide range of operating conditions. A dynamic thermal model for temperature estimation, and a typical electrical network using simple switch models for semiconductor devices have been implemented. The junction temperature is updated every switching cycle by the power loss with a thermal model and influence back to the electrical simulation. In this way, a closed-loop electro-thermal simulation is formed to evaluate both electrical and thermal performances in a single simulator with a range of acceptable accuracy. A double pulse test platform has been designed and built for device characterizations and power loss verifications. Moreover, a single-phase grid-tied buck-boost type inverter application has been selected as a case study and built to study the proposed method. The measured results indicate that the proposed approach is highly promising for power electronics engineers to evaluate and optimize a system during the early design stage.
Book Synopsis Thermal and Electro-Thermal System Simulation by : Márta Rencz
Download or read book Thermal and Electro-Thermal System Simulation written by Márta Rencz and published by MDPI. This book was released on 2019-11-18 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: With increasing power levels and power densities in electronics systems, thermal issues are becoming more and more critical. The elevated temperatures result in changing electrical system parameters, changing the operation of devices, and sometimes even the destruction of devices. To prevent this, the thermal behavior has to be considered in the design phase. This can be done with thermal end electro-thermal design and simulation tools. This Special Issue of Energies, edited by two well-known experts of the field, Prof. Marta Rencz, Budapest University of Technology and Economics, and by Prof. Lorenzo Codecasa, Politecnico di Milano, collects twelve papers carefully selected for the representation of the latest results in thermal and electro-thermal system simulation. These contributions present a good survey of the latest results in one of the most topical areas in the field of electronics: The thermal and electro-thermal simulation of electronic components and systems. Several papers of this issue are extended versions of papers presented at the THERMINIC 2018 Workshop, held in Stockholm in the fall of 2018. The papers presented here deal with modeling and simulation of state-of-the-art applications that are highly critical from the thermal point of view, and around which there is great research activity in both industry and academia. Contributions covered the thermal simulation of electronic packages, electro-thermal advanced modeling in power electronics, multi-physics modeling and simulation of LEDs, and the characterization of interface materials, among other subjects.

Abstract: With ever-decreasing device size and extensive use of energy-consuming smart devices, heat generated within devices easily leads to extremely high temperature. In return, high temperature influences electrical operational characteristics of the semiconductor devices. Therefore, it is essential for designers to predict accurate temperature and voltage/current distribution and its impact on various devices. For this purpose, coupled electro-thermal (ET) simulation is indispensable. Another concern lies in the number of matrix elements for computation, possibly millions of elements, resulting in days of heavy computation. Therefore, a fast yet accurate modeling framework of overcoming the simulation difficulty is required. In this dissertation, a new transient electro-thermal simulation method for fast 3D chip-level analysis of power devices with field solver accuracy is proposed. The metallization stack and substrate are meshed and solved with 3D field solver using nonlinear temperature-dependent electrical and thermal parameters, and the active transistors are modeled with table models to avoid time-consuming TCAD simulation. Three main contributions are made to enhance physical relevance and computational performance. First, both implicit loose and tight coupling schemes are introduced to compare their computational performances under different coupling degrees. Also, their complexity analysis is presented. Second, the capacitive effects, including interconnect parasitic capacitance and gate capacitance of power devices with nonlinear dependence on bias and temperature, are explicitly accounted for. The inclusion of capacitive effects allows accurate modeling of devices with large numbers of transistor fingers and high frequency application. Third, a specialized nonlinear exponential integrator (EI) method is developed to address the considerably different time scales between electrical and thermal sectors. The EI-based transient solver allows the electrical system to step with much larger time step size than in conventional methods, thus the time step size gap between the electrical and the thermal simulation is largely reduced. Its benefits of scalability, adaptivity and accuracy are also demonstrated in the dissertation. Subjects: Power semiconductors

Book Synopsis Power Electronics for Photovoltaic Power Systems by : Mahinda Vilathgamuwa
Download or read book Power Electronics for Photovoltaic Power Systems written by Mahinda Vilathgamuwa and published by Morgan & Claypool Publishers. This book was released on 2015-08-01 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world energy demand has been increasing in a rapid manner with the increase of population and rising standard of living. The world population has nearly doubled in the last 40 years from 3.7 billion people to the present 7 billion people. It is anticipated that world population will grow towards 8 billion around 2030. Furthermore, the conventional fossil fuel supplies become unsustainable as the energy demand in emerging big economies such as China and India would rise tremendously where the China will increase its energy demand by 75% and India by 100% in the next 25 years. With dwindling natural resources, many countries throughout the world have increasingly invested in renewable resources such as photovoltaics (PV) and wind. The world has seen immense growth in global photovoltaic power generation over the last few decades. For example, in Australia, renewable resources represented nearly 15% of total power generation in 2013. Among renewable resources, solar and wind account for 38% of generation. In near future, energy in the domestic and industrial sector will become ""ubiquitous"" where consumers would have multiple sources to get their energy. Another such prediction is that co-location of solar and electrical storage will see a rapid growth in global domestic and industrial sectors; conventional power companies, which dominate the electricity market, will face increasing challenges in maintaining their incumbent business models. The efficiency, reliability and cost-effectiveness of the power converters used to interface PV panels to the mains grid and other types of off-grid loads are of major concern in the process of system design. This book describes state-of-the-art power electronic converter topologies used in various PV power conversion schemes. This book aims to provide a reader with a wide variety of topologies applied in different circumstances so that the reader would be able to make an educated choice for a given application.
Book Synopsis Digital Control in Power Electronics by : Simone Buso
Download or read book Digital Control in Power Electronics written by Simone Buso and published by Morgan & Claypool Publishers. This book was released on 2015-05-01 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the reader, whether an electrical engineering student in power electronics or a design engineer, a selection of power converter control problems and their basic digital solutions, based on the most widespread digital control techniques. The presentation is primarily focused on different applications of the same power converter topology, the half-bridge voltage source inverter, considered both in its single- and three-phase implementation. This is chosen as the test case because, besides being simple and well known, it allows the discussion of a significant spectrum of the most frequently encountered digital control applications in power electronics, from digital pulse width modulation (DPWM) and space vector modulation (SVM), to inverter output current and voltage control, ending with the relatively more complex VSI applications related to the so called smart-grid scenario. This book aims to serve two purposes: (1) to give a basic, introductory knowledge of the digital control techniques applied to power converters; and (2) to raise the interest for discrete time control theory, stimulating new developments in its application to switching power converters.

This book was released on 2022-06-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computers play an important role in the analyzing and designing of modern DC-DC power converters. This book shows how the widely used analysis techniques of averaging and linearization can be applied to DC-DC converters with the aid of computers. Obtained dynamical equations may then be used for control design. The book is composed of two chapters. Chapter 1 focuses on the extraction of control-to-output transfer function. A second-order converter (a buck converter) and a fourth-order converter (a Zeta converter) are studied as illustrative examples in this chapter. Both ready-to-use software packages, such as PLECS® and MATLAB® programming, are used throught this chapter. The input/output characteristics of DC-DC converters are the object of considerations in Chapter 2. Calculation of input/output impedance is done with the aid of MATLAB® programming in this chapter. The buck, buck-boost, and boost converter are the most popular types of DC-DC converters and used as illustrative examples in this chapter. This book can be a good reference for researchers involved in DC-DC converters dynamics and control.
