| basic principles of soft switching: Reforming Rules and Regulations Vivek Ghosal, 2010-10-22 Experts examine how regulatory and institutional environments affect the functioning of markets and propose reforms. In recent years governments have paid increasing attention to weighing the socioeconomic benefits of regulations against their costs. Rules and regulations governing economic activity are typically formulated with a view to their benefits. Their effects on the costs and inefficiencies, in particular the possible chilling effects on competition and innovation, have received limited attention. In this collection, experts from Europe, the United States, and Asia examine a range of issues related to the effect of rules and regulations on competition, and explore the role of key institutions that affect market outcomes. Their contributions argue for using quantitative methods to guide policy and reform rules and regulation, and many of the essays offer methodologies for assessment and recommendations for policy alternatives.Topics covered include the effectiveness of R&D tax incentives in OECD countries; the adverse effect of EU climate policy on competitiveness; telecommunication regulation in the developing countries of India, China, and Sri Lanka; the role of banks in fostering small and medium enterprises in Argentina and Chile; the evolution of the U.S. Federal Home Loan Bank (FHLB) System; and developing quantitative screening tools to assess which sectors in the economy might benefit most from regulatory reforms.

| basic principles of soft switching: DC-DC Converter Topologies Gerry Moschopoulos, 2024-01-04 DC-DC Converter Topologies A comprehensive look at DC-DC converters and advanced power converter topologies for all skills levels As it can be rare for source voltage to meet the requirements of a Direct Current (DC) load, DC-DC converters are essential to access service. DC-DC power converters employ power semiconductor devices (like MOSFETs and IGBTs) as switches and passive elements such as capacitors, inductors, and transformers to alter the voltage provided by a DC source into the necessary DC voltage as is required by a DC load. This source can be a battery, solar panels, fuel cells, or a DC bus voltage fed by rectified AC utility voltage. As the many components of DC-DC converters can be differently arranged into circuit structures called topologies, there are as many possible circuit topologies as there are possible combinations of circuit elements. Focusing on DC-DC switch-mode power converters ranging from 50 W to 10kW, DC-DC Converter Topologies provides a survey of all converter topology types within this power range. General principles are described for each topology type using a representative converter as an example. Variations that can be found that differ from the example are then examined, with a helpful discussion of comparisons when relevant. A broad range of topics is covered within the book, from simple, low-power converters to complex, high-power converters and everywhere in between. DC-DC Converter Topologies readers will also find: A detailed discussion of four key DC-DC converter topologies Description of isolated two-switch pulse-width modulated (PWM) topologies including push-pull, half-bridge, and interleaved converters An exploration of high-gain converters such as coupled inductors, voltage multipliers, and switched capacitor converters This book provides the tools so that a non-expert will be equipped to deal with the vast array of DC-DC converters that presently exist. As such, DC-DC Converter Topologies is a useful reference for electrical engineers, professors, and graduate students studying in the field. |

| basic principles of soft switching: Autonomous Control of Unmanned Aerial Vehicles Victor Becerra, 2019-06-24 Unmanned aerial vehicles (UAVs) are being increasingly used in different applications in both military and civilian domains. These applications include surveillance, reconnaissance, remote sensing, target acquisition, border patrol, infrastructure monitoring, aerial imaging, industrial inspection, and emergency medical aid. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans. Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans. To make UAVs fully autonomous, many technological and algorithmic developments are still required. For instance, UAVs will need to improve their sensing of obstacles and subsequent avoidance. This becomes particularly important as autonomous UAVs start to operate in civilian airspaces that are occupied by other aircraft. The aim of this volume is to bring together the work of leading researchers and practitioners in the field of unmanned aerial vehicles with a common interest in their autonomy. The contributions that are part of this volume present key challenges associated with the autonomous control of unmanned aerial vehicles, and propose solution methodologies to address such challenges, analyse the proposed methodologies, and evaluate their performance. |
