Power electronics systems are nonlinear variable structure systems.
They involve passive components such as resistors, capacitors, and
inductors, semiconductor switches such as thyristors and MOSFETs,
and circuits for control. The analysis and design of such systems
presents significant challenges. Fortunately, increased
availability of powerful computer and simulation programs makes the
analysis/design process much easier. PSIM (R) is an electronic
circuit simulation software package, designed specifically for use
in power electronics and motor drive simulations but can be used to
simulate any electronic circuit. With fast simulation speed and
user friendly interface, PSIM provides a powerful simulation
environment to meed the user simulation and development needs. This
book shows how to simulate the power electronics circuits in PSIM
environment. The prerequisite for this book is a first course on
power electronics. This book is composed of eight chapters: Chapter
1 is an introduction to PSIM. Chapter 2 shows the fundamentals of
circuit simulation with PSIM. Chapter 3 introduces the Simview
(TM). Simview is PSIM's waveform display and post-processing
program. Chapter 4 introduces the most commonly used components of
PSIM. Chapter 5 shows how PSIM can be used for analysis of power
electronics circuits. 45 examples are studied in this chapter.
Chapter 6 shows how you can simulate motors and mechanical loads in
PSIM. Chapter 7 introduces the SimCoupler (TM). Simcoupler fuses
PSIM with Simulink (R) by providing an interface for co-simulation.
Chapter 8 introduces the SmartCtrl (R). SmartCtrl is a controller
design software specifically geared towards power electronics
applications.

DC-DC converters have many applications in the modern world. They
provide the required power to the communication backbones, they are
used in digital devices like laptops and cell phones, and they have
widespread applications in electric cars, to just name a few. DC-DC
converters require negative feedback to provide a suitable output
voltage or current for the load. Obtaining a stable output voltage
or current in presence of disturbances such as: input voltage
changes and/or output load changes seems impossible without some
form of control. This book tries to train the art of controller
design for DC-DC converters. Chapter 1 introduces the DC-DC
converters briefly. It is assumed that the reader has the basic
knowledge of DC-DC converter (i.e., a basic course in power
electronics). The reader learns the disadvantages of open loop
control in Chapter 2. Simulation of DC-DC converters with the aid
of Simulink (R) is discussed in this chapter as well. Extracting
the dynamic models of DC-DC converters is studied in Chapter 3. We
show how MATLAB (R) and a software named KUCA can be used to do the
cumbersome and error-prone process of modeling automatically.
Obtaining the transfer functions using PSIM (R) is studied as well.
These days, softwares are an integral part of engineering sciences.
Control engineering is not an exception by any means. Keeping this
in mind, we design the controllers using MATLAB (R) in Chapter 4.
Finally, references are provided at the end of each chapter to
suggest more information for an interested reader. The intended
audiencies for this book are practice engineers and academians.
Measurement is the process of obtaining the magnitude of a quantity
relative to an agreed standard. Electronic measurement, which is
the subject of this book, is the measurement of electronic
quantities like voltage, current, resistance, inductance, and
capacitance, to name a few. This book provides practical
information concerning the techniques in electronic measurements
and knowledge on how to use the electronic measuring instruments
appropriately. The book is composed of five chapters. Chapter 1
focuses on digital multimeters. You will learn how to use it for
measurement of AC/DC voltages/currents, resistance, connection
test, and diode forward voltage drop test. Chapter 2 focuses on
power supplies. Although power supplies are not a measurement
device, they have an undeniable role in many measurements. So,
being able to use power supplies correctly is quite important.
Chapter 3 focuses on function generators. Like the power supplies,
the function generators are not a measurement device in the first
look. However, they play a very important role in many electronic
measurements. So, being able to use a function generator correctly
is an important skill any technician or engineer needs. Chapter 4
focuses on oscilloscopes. These days, digital oscilloscopes are the
most commonly used tool in both industry and university. Because of
this, this chapter focuses on digital oscilloscopes not on the
analog ones which are almost obsolete. Chapter 5 focuses on drawing
graph of data you obtained from your measurement. Visualization of
data is very important in practical works. This chapter show how
you can use MATLAB (R) for drawing the graph of your measurements.
This book could be used a laboratory supplement for students of
electrical/mechanical/mechatronics engineering, for technicians in
the field of electrical/electronics engineering, and for anyone who
is interested to make electronic circuits.
Modeling is the process of formulating a mathematical description
of the system. A model, no matter how detailed, is never a
completely accurate representation of a real physical system. A
mathematical model is always just an approximation of the true,
physical reality of the system dynamics. Uncertainty refers to the
differences or errors between model and real systems and whatever
methodology is used to present these errors will be called an
uncertainty model. Successful robust control-system design would
depend on, to a certain extent, an appropriate description of the
perturbation considered. Modeling the uncertainties in the switch
mode DC-DC converters is an important step in designing robust
controllers. This book studies different techniques which can be
used to extract the uncertain model of DC-DC converters. Once the
uncertain model is extracted, robust control techniques such as and
synthesis can be used to design the robust controller. The book
composed of two case studies. The first one is a buck converter and
the second one is a Zeta converter. MATLAB (R) programming is used
extensively throughout the book. Some sections use PLECS (R) as
well. This book is intended to be guide for both academicians and
practicing engineers.
Simulation of Power Electronics Converters Using PLECS (R) is a
guide to simulating a power electronics circuit using the latest
powerful software for power electronics circuit simulation
purposes. This book assists engineers gain an increased
understanding of circuit operation so they can, for a given set of
specifications, choose a topology, select appropriate circuit
component types and values, estimate circuit performance, and
complete the design by ensuring that the circuit performance will
meet specifications even with the anticipated variations in
operating conditions and circuit component values. This book covers
the fundamentals of power electronics converter simulation, along
with an analysis of power electronics converters using PLECS. It
concludes with real-world simulation examples for applied content,
making this book useful for all those in the electrical and
electronic engineering field.
