Book Description :

The book introduces an original and effective method for the analysis of peak-to-peak output current ripple amplitude in three-phase two-level inverters. It shows that the method can be extended to both multiphase inverters, with particular emphasis on five-phase and seven-phase inverters, and multilevel ones, with particular emphasis on three-level inverters, and provides, therefore, a comparison among different number of output phases and voltage levels. The work reported on here represents the first detailed analysis of the peak-to-peak output current ripple. It makes an important step toward future developments in the field of high-power generation, and in grid-connected and motor-load systems.

Book Description :

Control schemes for inverters of different topologies and various numbers of voltage levels are of great interest for many standard as well as special applications. This thesis describes a novel, robust and high-dynamic direct current control scheme for multilevel voltage source inverters. lt is highly independent from load parameters and universally applicable. The new control method is examined and validated with real measurements . The aim of the thesis is to establish and prove a new concept of a direct current control algorithm for multilevel inverter topologies for grid connected systems. This application is characterized by unknown grid conditions including failure modes and other distortions, complex inverter topologies and a large variety and complexity of current control algorithms for multilevel inverters. Therefore the complexity of the system needs to be reduced. Additionally , the advantages of multilevel inverters and the dynamic performance and robustness of direct current control techniques shall be combined. Starting from a detailed literature study on inverter topologies and direct as well as indirect current control methods, the thesis includes three chapters containing relevant contributions to the achievement of the objectives. A method reducing the control-complexity of multilevel converters has been developed. The simplification method is based on a transformation that converts any three-phase voltage (or current) into a non-orthogonal coordinate system. This choice minimizes the complexity and effort to determine the location of those discrete voltage space vectors directly surrounding the required reference voltage vector. A further improvement is achieved by scaling all coordinates to integer values. This is advantageous for further calculations on microprocessors or FPGA based control systems. The main contribution of this thesis is a new direct current control method minimizing the disadvantages of existing direct methods. At the same time advantages of other control algorithms shall be applied. The new method is based on a simple mathematical equation, that is, the solution of a scalar product, to always select the one inverter output voltage vector best reducing the actual current error. This results in the designation "Scalar Hysteresis Control - SHC". An advanced seeking algorithm ensures robust current control capability even in case of unknown, unsymmetrical or changing loads, in case of rapid set-point changes or in cases of unknown phase voltages . The new method therefore shows excellent properties in terms of simplicity , robustness, dynamics and independence from the inverter level count and the hardware topology . The properties of the control method are verified by means of simulations and real measurements on two-, three- and five-level inverters over the complete voltage operating range. Finally, all contributions are collected together and assessed with regard to the objectives. From the proposed control method new opportunities for future work, further developments and extensions are evolving for continuing scientific research.

Book Description :

This book offers a general approach to pulse width modulation techniques and multilevel inverter topologies. The multilevel inverters can be approximately compared to a sinusoidal waveform because of their increased number of direct current voltage levels, which provides an opportunity to eliminate harmonic contents and therefore allows the utilization of smaller and more reliable components. On the other side, multilevel inverters require more components than traditional inverters and that increases the overall cost of the system. The various algorithms for multilevel neutral point clamped inverter fed induction motor are proposed and implemented, and the results are analyzed. The performance of these algorithms is evaluated in terms of inverter output voltage, current waveforms and total harmonic distortion. Various basic pulse width modulation techniques, features and implementation of space vector pulse width modulation for a two-level inverter, and various multilevel inverter topologies are discussed in detail. This book is extremely useful for undergraduate students, postgraduate students, industry people, scientists of research laboratories and especially for the research scholars who are working in the area of multilevel inverters. Dr. Satish Kumar Peddapelli is Assistant Professor at the Osmania University in Hyderabad, India. His areas of interest are Power Electronics, Drives, Power Converters, Multi Level Inverters and Special Machines.

Book Description :

DC/AC inversion technology is of vital importance for industrial applications, including electrical vehicles and renewable energy systems, which require a large number of inverters. In recent years, inversion technology has developed rapidly, with new topologies improving the power factor and increasing power efficiency. Proposing many novel approaches, Advanced DC/AC Inverters: Applications in Renewable Energy describes advanced DC/AC inverters that can be used for renewable energy systems. The book introduces more than 100 topologies of advanced inverters originally developed by the authors, including more than 50 new circuits. It also discusses recently published cutting-edge topologies. Novel PWM and Multilevel Inverters The book first covers traditional pulse-width-modulation (PWM) inverters before moving on to new quasi-impedance source inverters and soft-switching PWM inverters. It then examines multilevel DC/AC inverters, which have overcome the drawbacks of PWM inverters and provide greater scope for industrial applications. The authors propose four novel multilevel inverters: laddered multilevel inverters, super-lift modulated inverters, switched-capacitor inverters, and switched-inductor inverters. With simple structures and fewer components, these inverters are well suited for renewable energy systems. Get the Best Switching Angles for Any Multilevel Inverter A key topic for multilevel inverters is the need to manage the switching angles to obtain the lowest total harmonic distortion (THD). The authors outline four methods for finding the best switching angles and use simulation waveforms to verify the design. The optimum switching angles for multilevel DC/AC inverters are also listed in tables for quick reference. Application Examples of DC/AC Inverters in Renewable Energy Systems Highlighting the importance of inverters in improving energy saving and power-supply quality, the final chapter of the book supplies design examples for applications in wind turbine and solar panel energy systems. Written by pioneers in advanced conversion and inversion technology, this book guides readers in designing more effective DC/AC inverters for use in renewable energy systems.

Book Description :

The purpose of this book is to describe the theory of Digital Power Electronics and its applications. The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant. These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distortion. These new parameters result in the definition of new mathematical modeling: • A zero-order-hold (ZOH) is used to simulate all AC/DC rectifiers. • A first-order-hold (FOH) is used to simulate all DC/AC inverters. • A second-order-hold (SOH) is used to simulate all DC/DC converters. • A first-order-hold (FOH) is used to simulate all AC/AC (AC/DC/AC) converters. * Presents most up-to-date methods of analysis and control algorithms for developing power electronic converters and power switching circuits * Provides an invaluable reference for engineers designing power converters, commercial power supplies, control systems for motor drives, active filters, etc. * Presents methods of analysis not available in other books.

Book Description :

Control systems for three-phase grid connected voltage source inverters (VSI) play an important role in energy transformation systems . They are expected to be stable, robust and accurate during steady state as well as different grid faults and disturbances like voltage sags or unbalanced conditions. Caused by increasingly rising grid standards and efficiency requirements the use of multilevel inverter systems in grid connected low voltage applications are getting more and more attention. Nevertheless, the use of these inverter types leads to increased complexity of the control system and the hardware components. This thesis presents an improved control scheme for multilevel inverters in grid applications. The system combines a robust and high-dynamic direct current control scheme called scalar hysteresis.
