Power electronics is an application-oriented emerging area and finding applications in every day of our life in providing electric energy to sustain the usages of our modern electronic devices and equipment. The electric motors and auxiliary power of electric vehicles, solar energy, and other renewable energy sources require power electronics. With the increasing emphasis on renewable energy and energy savings in home, transportation, and industrial applications, power electronics education is becoming essential for supporting manpower needs for sustaining technological growth and development. Although power electronics is essential for powering modern devices, machines, and industrial equipment, Power electronics is normally offered in universities and colleges as a technical elective. It is an application-oriented and interdisciplinary course that requires a background in mathematics, electrical circuits, control systems, analog and digital electronics, microprocessors, electric power, and electrical machines. Power electronics deals with power processing from AC to DC, DC to AC, DC to DC, and AC to AC. Therefore, it requires a clear understanding of the performance parameters of the AC sources and loads, DC sources and loads, and the parameters of power electronic switching devices. Power electronics use power semiconductor devices as switching elements for transferring energy from the source to the load and vice versa. Due to the switching actions of the power electronic devices, the voltages and currents of the power electronic circuits are pulsing DC or DC waveforms. The understanding of the operation of a power electronics circuit requires a clear knowledge of the transient behavior of current and voltage waveforms for each circuit element at every instant of time. These features make power electronics a difficult course for students to understand and for professors to teach. However, Power electronics is playing a key role in power processing and control. This book is based on the author’s experience in teaching power electronics for many years and integrating design content and LTspice on power electronics. The book is intended for undergraduate students of engineering and engineering technology programs. It could be used by working engineers with some background in electric circuits and differential equations. The book considers power electronics consisting of piece-wise circuits. The book focuses on the LTspice circuit simulation and the performance analysis of the power electron circuits. The LTspice software, which is available free to students and professionals, is ideal for classroom use and for assignments requiring computer-aided simulation and analysis. Without any additional resources and lecture time, LTspice can also be integrated into power electronics. The objective of this book is to integrate the LTspice simulator with a power electronics course at the junior level or senior level with a minimum amount of time and effort. This book assumes no prior knowledge about the LTspice simulator. The simulation requires (a) a clear knowledge and understanding of the characteristics of the switching services, (b) the gating signal requirements of the devices to turn on and off of the devices to ensure the devices are fully turned on or off, (c) the generation of the gating signals to produce the desired waveforms of output voltages and currents, and (d) the insolation of the low-level gating signals from the high voltage and current circuits. The performance analysis requires (a) the determination of the modes of operation during a complete switching cycle or period, (b) the circuit models during the modes of operation, (c) developing mathematical models describing the voltage and current relations, (d) solving explicit equations of the circuit parameters, the boundary conditions and the switching time of the devices, the switching frequency, and the output frequency, and (d) determining the performance parameters of the converter, the input side parameters, and the output side parameters. This book can be divided into eight parts: (1) DC and AC Fundamentals – Chapter 1; (2) Switched RLC Circuits – Chapter 2; (3) Diode Rectifiers – Chapters 3; (4) DC–DC converters – Chapter 4; (5) AC–DC converters – Chapters 5; (6) Resonant Pulse Inverters – Chapters 6; (7) Controlled Rectifiers – Chapter 7; and (8) AC voltage controllers – Chapter 8.
