POWER ELECTRONICS A FIRST COURSE Enables students to understand power electronics systems, as one course, in an integrated electric energy systems curriculum Power Electronics A First Course provides instruction on fundamental concepts related to power electronics to undergraduate electrical engineering students, beginning with an introductory chapter and moving on to discussing topics such as switching power-poles, switch-mode dc-dc converters, and feedback controllers. The authors also cover diode rectifiers, power-factor-correction (PFC) circuits, and switch-mode dc power supplies. Later chapters touch on soft-switching in dc-dc power converters, voltage and current requirements imposed by various power applications, dc and low-frequency sinusoidal ac voltages, thyristor converters, and the utility applications of harnessing energy from renewable sources. Power Electronics A First Course is the only textbook that is integrated with hardware experiments and simulation results. The simulation files are available on a website associated with this textbook. The hardware experiments will be available through a University of Minnesota startup at a low cost. In Power Electronics A First Course, readers can expect to find detailed information on: Availability of various power semiconductor devices that are essential in power electronic systems, plus their switching characteristics and various tradeoffs Common foundational unit of various converters and their operation, plus fundamental concepts for feedback control, illustrated by means of regulated dc-dc converters Basic concepts associated with magnetic circuits, to develop an understanding of inductors and transformers needed in power electronics Problems associated with hard switching, and some of the practical circuits where this problem can be minimized with soft-switching Power Electronics A First Course is an ideal textbook for Junior/Senior-Undergraduate students in Electrical and Computer Engineering (ECE). It is also valuable to students outside of ECE, such as those in more general engineering fields. Basic understanding of electrical engineering concepts and control systems is a prerequisite.
This paper revisits the transmission of monetary policy by constructing a novel dataset of monetary policy shocks for an unbalanced sample of 33 advanced and emerging market economies during the period 1991Q2-2023Q2. Our findings reveal that tightening monetary policy swiftly and negatively impacts economic activity, but the effects on inflation and inflation expectations takes time to fully materialize. Notably, there exist significant heterogeneities in the transmission of monetary policy across countries and time, depending on structural characteristics and cyclical conditions. Across countries, monetary policy is more effective in countries with flexible exchange rate regime, more developed financial systems, and credible monetary policy frameworks. In addition, we find that monetary policy transmission is stronger when uncertainty is low, financial conditions are tight and monetary policy is coordinated with fiscal policy—that is, when the stances move in the same direction.
Emergency Musculoskeletal Imaging in Children is a practical, concise, and easy-to-read guide to the radiologic workup of acute musculoskeletal injuries and conditions in children. The book is conveniently organized by anatomic site and covers all acute injuries and conditions of the upper and lower extremities encountered in the emergency room, outpatient clinic, and office. Close attention is also given to normal findings and anatomic variants that can mimic pathology. More than 600 MR, CT, ultrasound, and radiographic images complement the text.
This book provides a theoretical discussion of pulse width modulation (PWM) in power electronic inverters. Pulse width modulation is widely used for the frequency control of speed of ac motors, the design of uninterruptible power supplies (UPS) as well as the integration of renewable energy sources into existing power grid systems. PWM technique is based on approximation of sinusoidal waveforms by sequences (trains) of rectangular pulses whose widths are properly modulated. This width-modulation results in the suppression of low order harmonics at the expense of amplification of high order harmonics which are suppressed by energy-storage elements in load circuits. The discussion covers various PWM techniques with a focus on the optimal time-domain PWM techniques proposed by the authors.
