Power electronic

Power electronics is the technology of processing and controlling the flow of electric energy by supplying voltages and currents in a form that is optimally suited to the end-user’s requirements [1].Atypical block diagram is given in Figure 1.1 [2]. The input power can be either AC and DC sources. A general example is one in which the AC input power is from the electric utility. The output power to the load can be either AC and DC voltages. The power processor in the block diagram is usually called a converter. Conversion technologies are used to construct converters.

This book is mainly intended for designers and users of magnetic components in power electronics. It can also be used for didactical purposes. Magnetic components such as inductors and transformers constitute together with the control and the semiconductor components, the main parts in the design of power electronic converters. Some experience teaches that the design of the magnetic parts is still often done by trial and error. This can be explained by a (too) long working-in time for designing inductors and transformers.

Power electronic converters (PECs) are static devices, without any movable parts, that convert electric energy of one set of properties into electric energy of another, different set of properties. The properties that are changed by the action of the converter are one or more of the following: number of phases, frequency, and voltage rms (or average, in the DC case) value. Thus any power electronic converter is essentially a transformer in a broad sense. Action of a power electronic converter is illustrated in Fig....

In this chapter, we review power electronic converters used in ASDs with induction motors. Various types of rectifiers providing the dc supply voltage for inverters feeding the motors are presented, and we describe voltage source inverters, including three-level and soft-switching inverters, and current source inverters. Control methods for inverters, with a stress on the use of voltage space vectors, are illustrated. Finally, we outline undesirable side effects of the switching operation of power converters.

Harmonic distortion problems include equipment overheating, motor failures, capacitor failure and inaccurate power metering. The topic of power system harmonics was covered for the first time 20 years ago and the first edition has become a standard reference work in this area. Unprecedented developments in power electronic devices and their integration at all levels in the power system require a new look at the causes and effects of these problems, and the state of hardware and software available for harmonic assessment.

Electrical consumption, especially direct or variable frequency currents, has strongly increased over 50 years in industry. This situation explains the growth of power electronics. At the beginning, when rectifiers replaced DC machines, only diodes and thyristors were used. Then power transistors appeared and enabled the extension of smaller power applications for domestic use. New research topics were developed around converters and power devices.

In practice, consumption devices are not only resistive but also reactive and this reactance varies with time. Therefore, grid voltage is not stable and coefficients always change in spite of using Automatic Reactive Power Regulator. To regulate voltage and cosφ in an expected range, it is necessary to change the parameters of regulators as the loads change.

PSAT is a Matlab toolbox for static and dynamic analysis and control of electric power systems. The PSAT project began in September 2001, while I was a Ph.D. candidate at the Universit´ degli Studi di Genova, Italy. The first public a version date back to November 2002, when I was a Visiting Scholar at the University of Waterloo, Canada. I am currently maintaining PSAT in the spare time, while I am working as associate professor at the Universidad de Castilla-La Mancha, Ciudad Real, Spain. PSAT is provided free of charge, in the hope it can be useful and other people...

Theo nghĩa rộng, nhiệm vụ của điện tử công suất là xử lý và điều khiển dòng năng lượng điện bằng cách cung cấp điện áp và dòng điện ở dạng thích hợp cho các tải. Tải sẽ quyết định các thông số về điện áp, dòng điện, tần số, và số pha tại ngõ ra của bộ biến đổi. Thông thường, một bộ điều khiển có hồi tiếp sẽ theo dõi ngõ ra của bộ biến đổi và cực tiểu hóa sai lệch giữa giá trị thực của ngõ ra và giá trị mong muốn (hay giá trị đặt)....
