Power Electronic converters have been used in wide range of applications including home appliances, computers and telecommunication systems, motor drives and renewable energy systems.
The main aim of publishing this book is to serve as a textbook for undergraduate and postgraduate students who study Power Electronics or Advanced Industrial Electronics subject or as a reference book for development engineers who practice power electronics design.
I would like to thank Dr. Alireza Nami, Dr. Arash Abbasalizadeh Boora and Dr. Jafar Adabi Firouzjaee who contributed in preparing the following chapters.
This book consists of three main chapters which addresses important topics in Power Electronics such as:
1: Multilevel Converter Topologies
This chapter describes traditional multilevel converter topologies with different switching transients and voltage control of capacitors. It also covers multilevel converters with new DC link configurations to generate more voltage levels. In the final section, hybrid multilevel converters with new and traditional DC link configurations are discussed.
Authors: Dr. Alireza Nami, Prof. Firuz Zare
2: Single Inductor Multi-output DC-DC Converters
This chapter is focused on single inductor multi-output DC-DC converters with series and parallel load configurations and based on three traditional DC-DC converters: Buck, Boost and Positive Buck Boost converters. Different operating modes of each converter have been analysed based on different switching states and using state-space averaged equations.

3: Analysis of Common Mode and Shaft Voltages in AC Motor Drive Systems
The third chapter is about common mode voltage and shaft voltage issues in AC motor drive systems. In the first part of this chapter,
three-phase pulse width modulated voltage waveforms (leg, line and common mode voltages) generated by a power converter are analysed. In the second part of this chapter, some methods to extract capacitive couplings between windings, stator and rotor are described. Finally, a high frequency model of an AC motor is discussed to calculate shaft voltage and conducted emission noise.
