An invaluable academic reference for the area of high-power converters, covering all the latest developments in the field

High-power multilevel converters are well known in industry and academia as one of the preferred choices for efficient power conversion. Over the past decade, several power converters have been developed and commercialized in the form of standard and customized products that power a wide range of industrial applications. Currently, the modular multilevel converter is a fast-growing technology and has received wide acceptance from both industry and academia. Providing adequate technical background for graduate- and undergraduate-level teaching, this book includes a comprehensive analysis of the conventional and advanced modular multilevel converters employed in motor drives, HVDC systems, and power quality improvement.

Modular Multilevel Converters: Analysis, Control, and Applications provides an overview of high-power converters, reference frame theory, classical control methods, pulse width modulation schemes, advanced model predictive control methods, modeling of ac drives, advanced drive control schemes, modeling and control of HVDC systems, active and reactive power control, power quality problems, reactive power, harmonics and unbalance compensation, modeling and control of static synchronous compensators (STATCOM) and unified power quality compensators. Furthermore, this book:

• Explores technical challenges, modeling, and control of various modular multilevel converters in a wide range of applications such as transformer and transformerless motor drives, high voltage direct current transmission systems, and power quality improvement
• Reflects the latest developments in high-power converters in medium-voltage motor drive systems
• Offers design guidance with tables, charts graphs, and MATLAB simulations

Modular Multilevel Converters: Analysis, Control, and Applications is a valuable reference book for academic researchers, practicing engineers, and other professionals in the field of high power converters. It also serves well as a textbook for graduate-level students.

CHAPTER 1
REVIEW OF HIGH-POWER CONVERTERS

1.1 INTRODUCTION

Power converters are well known in industries and the academia as one of the preferred choices for high-efficiency, electric power conversion systems. For the past few years, several power converters were developed and commercialized in the form of standard and customized products. These converters power a wide range of industrial applications such as pumps, compressors, fans, mills, conveyors, transportation (e.g., electric vehicles and, railway traction), manufacturing, petrochemical, high-voltage direct current (HVDC) transmission, reactive power compensation, and wind energy conversion systems [1–3].

This chapter deals with state-of-the-art and recent advancements in high-power converter topologies. The classification of high-power converters is presented in Section 1.2. The first category of power converters uses an intermediate DC-link to achieve the power conversion from fixed AC to variable AC supply. Based on the type of intermediate DC-link, power converters are categorized into voltage source converters (VSC) and current source converters (CSC). A brief description of VSC and CSC topologies is presented in Sections 1.3 and 1.4, respectively. An alternative approach is the direct power conversion from fixed AC to variable AC without any intermediate DC-link. Cycloconverters (CCV) and matrix converters (MC) belong to this category. The circuit configuration and operation of these topologies are presented in Section 1.5.

Voltage source converters have the highest market share and are widely used in industries. Several VSCs were developed in the past years. Among them, modular multilevel converter (MMC) is a highly regarded topology, which is the main focus of this book. The modular multilevel converter has several features such as modular construction, high reliability, and cost-effectiveness because it uses low-voltage, insulated gate bipolar transistor (LV-IGBT) technology to reach high-voltage (HV) operation. MMC is directly connected to medium-voltage (MV) and high-vol...
