1. 1. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Erik Nordlund; [2023]
   Keywords : Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

   Abstract : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance.

3. 2. Investigation of Resistive Random Access Memory for 1T1R Nanowire Array Integration

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Orestes Theodoridis; [2020]
   Keywords : RRAM; Nanowire; Memory Technology; Nanoelectronics; Nanoscience; Physics and Astronomy;

   Abstract : As modern electronics have started to reach its physical scaling limits, novel architectures and physics is needed to meet future demands. Oxide-based Resistive Random Access Memory (RRAM) is a new emerging technology that uses filament formation and rupture in thin oxides to generate resistive switching. READ MORE

4. 3. Low Power Current Sensing Node Powered by Harvested Stray Electric Field Energy

   University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

   Author : Björn Holby; Carl-Fredrik Tengberg; [2015]
   Keywords : Energy Harvesting; Low Power; Sensor; Wireless Communication;

   Abstract : In this thesis, the possibility of harvesting energy from a multicore power cableconnected to a power outlet is presented and evaluated. By surrounding a powercable with a conductive material connected to ground, it is shown that the dif-ference in potential between the power cable and the conductive material causesa capacitance which can charge a capacitor that in combination with an energymanagement circuit can be used to wirelessly transmit data with an interval de-pending on factors like the length of the surrounding material and the type ofcable it is placed around.

5. 4. Area Efficient ADC for Low Frequency Application

   University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska högskolan

   Author : Abdul Wahab Sami; [2014]
   Keywords : Cyclic ADC; Sample and Hold; Multiply-By-Two-Amplifier; Bottom Plate Sampling; OTA; Area; Low power.;

   Abstract : Analog to digital converters (ADCs) are the fundamental building blocks in communication systems. The need to design ADCs, which are area and/or power efficient, has been common. Various ADC architectures, constrained by resolution capabilities, can be used for this purpose. READ MORE

6. 5. Input Filter to Prevent Line Oscillations in Buck Converter

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Raghavendra Pappala; Raghavender Reddy Naredla; [2013]
   Keywords : Filter design; Line Oscillations; Buck Converter; Damping; Passive Filter;

   Abstract : Micropower AB is a company that design and produce battery chargers for heavy vehicles. Buck converters are used in some chargers as they provide a regulated output voltage. In buck converter, transistor acts as a switch which is controlled by Pulse Width Modulated signal. READ MORE
