This book was released on 2007 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the presence of grid voltage harmonics, an AC-DC-AC drive with conventional fundamental frequency control experiences large line current harmonics, and in the case of a minimized DC link capacitance, large DC link voltage ripple harmonics. This thesis presents and compares two control methodologies that overcome this problem and suppress the effects of grid voltage harmonics on AC-DC-AC converters with minimized DC link capacitance. The first harmonic mitigation controller is implemented via multiple synchronous frame control structure somewhat similar to those used in active power filter applications. The other harmonic mitigation controller is realized in the stationary frame with several variations to the controller via the inclusion of cross-coupling control and feedback terms.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transportation sector is gaining much more attention towards all-electric modes such as electric vehicles (EV), and more electric aircrafts and ships. EVs lead the transportation sector with luxurious, high performance, and intelligent vehicles. The stored battery energy is the most important factor for the operation of the whole vehicle and therefore, EV battery chargers play an important role in the electric transportation sector. High frequency isolated battery charger converters are much preferred in the industry as they provide electrical isolation and reduce magnetic component size. Phase shifted pulse width modulation is commonly used in transformer isolated converters for high frequency power transfer. Generally, the voltage waveforms are phase shifted no more than 45 degrees for grid connected converter applications. In grid connected applications, the high frequency pulse widths (180° to minimum determined by modulation index) may vary when controlling the grid current. If, for certain duration of the low frequency reference signal, the pulse widths are smaller than the externally-commanded phase shift, the pulses would be completely separated. Under these conditions, unwanted reactive content is generated in the converter increasing the high frequency rms current hence increasing conduction losses. An original concept is proposed to lower the reactive content of the high frequency current by positioning the transformer primary and secondary voltage pulses next to each other whenever the phase shift is larger than the pulse width. The voltage pulses are positioned appropriately in each carrier cycle throughout the entire low frequency reference signal. This concept which is referred to as reference-based pulse position (RPP) allows the operation of the converter beyond 45 degree limit and up to 90 degrees allowing for more power output. The concept is tested on an isolated single-stage bidirectional three-phase ac-dc converter which conducts both low frequency grid current and high frequency transformer current. The grid side or the primary of the converter generates the high frequency transformer voltage when controlling the grid current. The switches in the secondary side are then controlled in such a way in each carrier cycle as to coordinate with primary voltage waveform to minimize the reactive content of the high frequency current. The power is transferred utilizing the transformer interlimb leakage inductance. The transformer windings are connected so that the 60Hz grid current does not produce flux in the core leaving only the high frequency flux. Therefore, the size of the magnetics can be reduced which favors a compact design. Furthermore, the dc link utilization is maximized by injecting the third harmonic into the sine reference signals which lowers the dc link requirement by 15%.
Book Synopsis Resonant Power Converters by : Marian K. Kazimierczuk
Download or read book Resonant Power Converters written by Marian K. Kazimierczuk and published by John Wiley & Sons. This book was released on 2012-11-07 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to resonant energy conversion in power electronics. It is a practical, systematic guide to the analysis and design of various dc-dc resonant inverters, high-frequency rectifiers, and dc-dc resonant converters that are building blocks of many of today's high-frequency energy processors. Designed to function as both a superior senior-to-graduate level textbook for electrical engineering courses and a valuable professional reference for practicing engineers, it provides students and engineers with a solid grasp of existing high-frequency technology, while acquainting them with a number of easy-to-use tools for the analysis and design of resonant power circuits. Resonant power conversion technology is now a very hot area and in the center of the renewable energy and energy harvesting technologies.

Book Synopsis Digital Power Electronics and Applications by : Fang Lin Luo
Download or read book Digital Power Electronics and Applications written by Fang Lin Luo and published by Elsevier. This book was released on 2010-07-20 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
