Neacsu D. Switching Power Converters. Medium and High Power 3ed 2026

Textbook in PDF format The Third Edition of Switching Power Converters goes beyond the design and analysis of conventional power converter circuits to discuss the actual use of industrial technology, covering facets of implementation otherwise overlooked by theoretical textbooks. This edition uniquely presents the historical and market evolution of each technology, allowing the reader to follow trends. Power electronics represents a mature technology, with a variety of products concurrent on the market, designed and launched from the 1990s to 2020s. The theoretical aspects presented in the book are supported with many examples, diligently exemplifying this market complexity. It highlights advancements in new semiconductor devices and packaging technologies, design for reliability, or computer utilization in the design, development, and validation of new technical solutions. It also examines all of the multidisciplinary aspects of medium- and high-power converter systems, including basic power electronics, digital control and hardware, sensors, analog preprocessing of signals, protection devices and fault management, and pulse width modulation (PWM) algorithms. The biggest difference from the other fields of electronics is the power coordinate. If students learn about a circuit or method for any other class of applications of electronics, they can easily manage to debug or put into service versions of that circuit from different manufacturers or within different applications. Power electronic circuits and their applications, however, are very different. The topology of a three-phase rectifier equipped with thyristors can be used for a 500 MVA HVDC transmission line or for a 1 kW welding machine. We can understand the basic operation of the three-phase phase-controlled rectifier from a college textbook, but the two systems are extremely different in reality. Each thyristor circuit explained in the textbook has a different implementation in practice, ranging from a half-inch T0–220 package to a building of six floors. The protection circuits are also very different and range from no protection at all to sets of computer-controlled panels and automatic hot-swap replacement units. Finally, the cooling system could range from environmental air to complex systems of pumps or fans that by themselves have large installed power, often controlled with variable frequency through power electronics equipment. The core of any power electronic converter is the control algorithm, and multiple options for pulse width modulation (PWM) algorithms are detailed in the book. The implementation possibilities for these control methods are shown from a historical perspective to allow the reader to understand that the semiconductor technology embedded in microcontrollers influence continuously the way we think about the PWM algorithms. Introduction of new bandgap power semiconductors increased the switching frequency, electrification of appliances, forced satisfaction of grid standards, and so on. Each class of converters is dedicated a separate chapter, including topologies that are in demand by industry as well as topologies that lost their appeal somewhat while they still offer a huge academic and educational benefit. Similar to the previous two editions, the Third Edition of Switching Power Converters remains the go-to-book for understanding all aspects related to the PWM used in the control of power converters. This book is one of the most comprehensive presentations of PWM algorithms, with illustrations of practical results for optimization or implementation on each analog, software, digital hardware, or Gbit flash memory platform.
