1. Power-sourced charging over PoE to enable high power peaks
Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : In contrast with well-known traditional Closed Circuit Television cam-eras, nowadays most electronic devices including Internet Protocol surveil-lance cameras , Wireless Access Point, Network Routers, Voice over Internet Protocol technologies ,and so forth are all powered throughPower over Ethernet cables. These cables are capable of delivering bothDirect Current power and data simultaneously using a single main cable for the Local area network, this tremendously assisted system integra-tors and network installers to deploy electronic devices in locations that lack electrical circuitry and eventually eliminating the extra expensesof installing additional electrical wiring as well as power supplies.

2. Reconnaissance Radar Robot
Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : During the last century, various countries' armed forces have used unmanned aerial vehicles, commonly known as drones. In recent years, strives have been made to develop small commercial drones that have allowed the general public to afford and use them for recreational purposes. LÄS MER
3. Exploring Ethernet Switching Architectures for Area-Efficient Low-End Switches
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The aim of this thesis project has been to develop an architecture for L2 ethernet switches that would be optimized for silicon area, targeting smaller low-end switches. A selection was made of three different switching architectures, which were compared and analyzed to explore the benefits and drawbacks of different approaches. LÄS MER
4. Closed-loop control and data- recording of a modular-multilevel converter (MMC)
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. LÄS MER
5. A Generic Software Architecture for PoE Power Sourcing Equipment
Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknikSammanfattning : The IEEE Power over Ethernet (PoE) protocol is currently the most used standard for allowing Power Sourcing Equipment (PSE) to distribute power to Powered Devices (PD) through standard Ethernet cables, permitting devices to be added to a network without needing extra power cables.There exist many PSE manager circuits which can be used to easily distribute power to a handful of PDs, but a problem arises when more are desired, since very few of these circuits can communicate with other circuits, and thus can't coordinate power distribution with each other.
