    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Dhruvi Ajit Shukla; [2022]
    Keywords : Wireless Power Transfer WPT ; ferrites; Litz wire; skin effect; proximity effect; electromagnetic induction; electromagnetic resonance; magnetic coupling; power efficiency; LC circuits; Trådlös kraftöverföring WPT ; ferrit; litz-tråd; hudeffekt; närhetseffekt; elektromagnetisk induktion; elektromagnetisk resonans; magnetisk koppling; effekteffektivitet; LC-kretsar;

    Abstract : This thesis deals with wireless power transfer from an external source to embedded small devices (such as for conditioning monitoring, control etc.) located at different distances from the source. The proposed designs can be used in a variety of applications, including mobile phones, electric cars, unmanned aerial vehicles, robots, etc. READ MORE

  3. 2. Methods to simulate resistance at high resolution and accuracy

    University essay from Uppsala universitet/Elektricitetslära

    Author : Ola Jansson; [2021]
    Keywords : variable resistance; digital potentiometer; potentiometer; simulate; resistance; variabel resistans; digital potentiometer; potentiometer; simulera; resistans;

    Abstract : In this paper, four methods to simulate or generate electric resistance at high resolution have been developed, tested and evaluated. Each method is called a Resistor Simulator and are numbered from one to four. READ MORE

  4. 3. Design of a 16 GSps RF Sampling Resistive DAC with on-chip Voltage Regulator

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Pontus Thomsson; Cyrus Seyed Aghamiri; [2021]
    Keywords : DAC; LDO; RDAC; 16GSps; 12-bit; Digital-to-Analog Converter; Low-Dropout Regulator;

    Abstract : Wireless communication technologies continue to evolve to meet the demand for increased data throughput. To achieve higher data throughput one approach is to increase the bandwidth. One problem related to very large bandwidths is the implementation of digital-to-analog converters with sampling rates roughly in the 5 to 20 GHz range. READ MORE

  5. 4. Evaluation of thermal expansion in busbars used for battery electric vehicles

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FREDRIK LARSSON; [2021]
    Keywords : Busbar; Battery electric vehicle; Thermal expansion; Cross-section shape;

    Abstract : Thermal expansion can be an issue in solid busbars, the expansion is caused by several factors and can cause plastic deformation in connection points or structure around it. The expansion occurs due to temperature differences in the busbar as a result of altered ambient temperature and/or joule heating. READ MORE

  6. 5. Analysis of Heating Processes for the Production of Bipolar Plates in PEM Fuel Cells

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : LASSE MATTHIAS REINPOLD; [2020]
    Keywords : ;

    Abstract : Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative to combustion engines and batteries in vehicles. PEMFCs are more efficient than combustion engines, and cars powered by PEMFCs tend to have longer ranges than battery powered cars and has a short fuelling time. READ MORE
