ELECTRIMACS 2019
This book collects a selection of papers presented at ELECTRIMACS 2019 - The 13th international conference of the IMACS TC1 Committee, held in Salerno, Italy, on 21st-23rd May 2019. The conference papers deal with modelling, simulation, analysis, control, power management, design optimization, identification and diagnostics in electrical power engineering. The main application fields include electric machines and electromagnetic devices, power electronics, transportation systems, smart grids, electric and hybrid vehicles, renewable energy systems, energy storage, batteries, supercapacitors and fuel cells, wireless power transfer. The contributions included in Volume 2 are particularly focussed on methodological aspects, modelling and applied mathematics in the field of electrical engineering.
Modular Multilevel Converters with Interleaved Half-Bridge Submodules
This book reports on a comprehensive study on a novel high-power converter, i.e. a Modular Multilevel Converter with Interleaved Half-bridge Submodules (ISM-MMC). It describes in depth its average model, the operating principles, as well as a new control method and a hybrid modulation strategy that help to exploit the benefits of the interleaving scheme. The new power converter is particularly advantageous for high-current applications that require superb quality of input/output waveforms. Moreover, this book reports on a systematic study of the current balancing problem between parallel-connected units that commutate in non-simultaneous fashion. This is a typical issue in interleaved conver...
Politique et Société en Sicile, XIIe-XVe Siécles
In the 12th century, under its Norman rulers, Sicily stood as one of the most flourishing regions of the Mediterranean; by the late 15th century it had sunk into the state of semi-colonial depression and dependence that has chartacterized so much of its modern history. It is this transformation ” a process of socio-economic change that went hand in hand with political turmoil ” that forms the subject of this volume. Henri Bresc approaches this both from the viewpoint of particular topics, such as the notarial class or the tiny island of Pantelleria, and that of larger themes. One of these is the composition of Sicily's population. These articles trace the deteriorating status of the Arab...
Autonomous Control of Unmanned Aerial Vehicles
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 de...
Applications of Power Electronics
Power electronics technology is still an emerging technology, and it has found its way into many applications, from renewable energy generation (i.e., wind power and solar power) to electrical vehicles (EVs), biomedical devices, and small appliances, such as laptop chargers. In the near future, electrical energy will be provided and handled by power electronics and consumed through power electronics; this not only will intensify the role of power electronics technology in power conversion processes, but also implies that power systems are undergoing a paradigm shift, from centralized distribution to distributed generation. Today, more than 1000 GW of renewable energy generation sources (phot...
Design and Control of Power Converters 2019
In this book, 20 papers focused on different fields of power electronics are gathered. Approximately half of the papers are focused on different control issues and techniques, ranging from the computer-aided design of digital compensators to more specific approaches such as fuzzy or sliding control techniques. The rest of the papers are focused on the design of novel topologies. The fields in which these controls and topologies are applied are varied: MMCs, photovoltaic systems, supercapacitors and traction systems, LEDs, wireless power transfer, etc.
Peak-to-Peak Output Current Ripple Analysis in Multiphase and Multilevel Inverters
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.

Level Doubling Network and Ripple Correlation Control MPPT Algorithm for Grid-Connected Photovoltaic Systems
This book describes an original improvement in power quality of photovoltaic generation systems obtained by the use of a multilevel inverter implemented with level doubling network (LDN). Modulation principles and harmonic analysis of output voltages are proposed and introduced in detail for both single and three-phase LDN configurations. The analysis is then extended to dc-link current and voltage, with emphasis to low-frequency harmonics and switching frequency ripple. This work represents the first comprehensive implementation of maximum power point tracking (MPPT) schemes using the ripple correlation control (RCC) algorithm in the presence of multiple ripple harmonics, such as in the case of multilevel inverters. Numerical simulations and experimental tests are carefully reported here, together with practical insights into the design of dc-link capacitors.
