Beschreibung

Designed to complement a range of power electronics study resources, this unique lab manual helps students to gain a deep understanding of the operation, modeling, analysis, design, and performance of pulse-width modulated (PWM) DC-DC power converters. Exercises focus on three essential areas of power electronics: open-loop power stages; small-signal modeling, design of feedback loops and PWM DC-DC converter control schemes; and semiconductor devices such as silicon, silicon carbide and gallium nitride. Meeting the standards required by industrial employers, the lab manual combines programming language with a simulation tool designed for proficiency in the theoretical and practical concepts. Students and instructors can choose from an extensive list of topics involving simulations on MATLAB, SABER, or SPICE-based platforms, enabling readers to gain the most out of the prelab, inlab, and postlab activities. The laboratory exercises have been taught and continuously improved for over 25 years by Marian K. Kazimierczuk thanks to constructive student feedback and valuable suggestions on possible workroom improvements. This up-to-date and informative teaching material is now available for the benefit of a wide audience. Key features: * Includes complete designs to give students a quick overview of the converters, their characteristics, and fundamental analysis of operation. * Compatible with any programming tool (MATLAB, Mathematica, or Maple) and any circuit simulation tool (PSpice, LTSpice, Synopsys SABER, PLECS, etc.). * Quick design section enables students and instructors to verify their design methodology for instant simulations. * Presents lab exercises based on the most recent advancements in power electronics, including multiple-output power converters, modeling, current- and voltage-mode control schemes, and power semiconductor devices. * Provides comprehensive appendices to aid basic understanding of the fundamental circuits, programming and simulation tools. * Contains a quick component selection list of power MOSFETs and diodes together with their ratings, important specifications and Spice models.

Preface

The Laboratory Manual for Pulse-Width Modulated DC–DC Power Converters is intended to aid undergraduate and graduate students of electrical engineering, practicing engineers, scientists, and circuit designers to have a grasp on designing and simulating a variety of fundamental and advanced power electronic circuits. The manual enables users to get accustomed to different simulation tools such as MATLAB®, Synopsys SABER®, LTSpice®, PLECS®, or any other Spice-based circuit simulation platforms. The approach presented in this manual will enhance a student's understanding of different power electronic converters and also gain knowledge in great depth on performing circuit simulations; a characteristic needed for a career in electrical engineering.

This manual is a supplementary material to the successful edition of the textbook Pulse-width Modulated DC–DC Power Converters, Second Edition, authored by Prof. Marian K. Kazimierczuk. The lab manual complements the content of the textbook and the combination of the two is a one-stop arrangement for students and instructors to gain the most about power electronic circuits and their simulation. This book features the following attributes:

Unique in the market of textbooks for power electronics.

Can be adopted as a supplementary material for any commercially available textbooks on power electronics as well as classnotes.

Can be used for distance-learning power electronic course or e-learning.

The software-oriented approach makes it convenient for students to have take-home assignments.

Simple and easy-to-understand procedure set.

Provides a quick overview of various power converters and components.

The purpose of the Laboratory Manual for Pulse-Width Modulated DC–DC Power Converters is to provide a comprehensive instruction set for the following:

To design and simulate various topologies of power electronic dc–dc converters such as boost and boost-derived, buck and buck-derived, flyback, forward, half-bridge, and full-bridge converter topologies, operating in continuous-conduction mode or discontinuous-conduction mode.

To simulate the small-signal models of the power electronic circuits and to understand the different small-signal characteristics of boost and buck converters operating in continuous-conduction mode.

To understand the properties of silicon, silicon-carbide, and gallium-nitride power MOSFETs used in power electronic applications.

The topics presented in this lab manual have been thoughtfully considered, keeping in mind the benefits it offers to the students. The primary author of this lab manual has been teaching specialized graduate-level courses in power electronics for more than 25 years. Since then, consistent effort has been put into creating equally interesting and accurate lab curricula for the students. The outcome of that dedication has been this lab manual. The experiments in this manual have been tested and updated regularly for technical correctness and clarity in the presentation style. The authors of this book recommend the below instructions for instructors and students in making the best use of this manual.

For Instructors

Instructors involved in teaching power electronic courses can adopt this lab manual as a required course material. The lab manual consists of three parts:

PART I—Open-Loop Pulse-Width Modulated DC–DC Power Converters

PART II—Closed-Loop Pulse-Width Modulated DC–DC Power Converters

PART III—Semiconductor Materials and Power Devices

Part I consists of 28 lab experiments. Part II has 16 lab experiments. Part III offers 6 lab experiments with several subsections. For an undergraduate power electronic course offered once an academic year, instructors can adopt selected lab topics from all of the three parts. For graduate programs offering specialized power electronic courses and taught for more than one semester, instructors may plan to dedicate a single part for every semester. The post-lab exercise will aid in summarizing the lab activity that was performed and provides a background for the consecutive labs. The students must be encouraged to follow the format of lab report at the end of the Appendix. Following such a format will aid in improving the students' technical communication and problem solving skills as well as their professional writing capabilities.

For Students

The lab manual assumes that the student is familiar with general circuit analysis techniques, electronic circuits, and the basic know-how of simulation tools. Every lab topic includes a pre-lab section. Students are encouraged to understand the circuit operation, calculate the component values, and also understand the design process of the converter under consideration. It is expected that the students follow every step in the procedure section for successful completion of the lab topic. The quick design section provides data about the component values and component selection that students can use for rapid verification. The Appendix has been made very resourceful and provides the following information:

Detailed summary of design equations for buck, boost, buck–boost, flyback, forward, half-bridge, and full-bridge converter in continuous-conduction mode and discontinuous-conduction mode.

Instructions on using MATLAB®, Synopsys SABER®, and other Spice-based simulation tools.

Spice models of several power diodes and power MOSFETs needed for component selection.

A summary of physical constants, values of different properties of silicon (Si), silicon-carbide (SiC), and gallium-nitride (GaN) semiconductor materials and power devices.

Format and guidelines to prepare a well-organized lab report.
