  1. 1. Self-Tuning NFC Circuits

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Yimeng Li; [2017]
    Keywords : Parallel capacitance compensation; RFID system; NFC; Self-tuning NFC; Digitally tunable capacitor;

    Abstract : Contactless automatic identification procedures which are called RFID systems (Radio-frequency Identification) have become very popular in recent years for transferring power and data. With the development of RFID technology, the demand of easy transmitting of short data packages has made NFC (Near-field Communication) technology wildly used especially in mobile applications.

  3. 2. Life Cycle Assessment development for electrified roads : Case study for Sweden

    University essay from KTH/Byggvetenskap

    Author : Réka Nádasi; [2017]
    Keywords : LCA; SimaPro; eRoad; IPT; Conductive track; Pantograph; Sustainability;

    Abstract : The increasing role of sustainability will lead the mobility by road into a more efficient and interactive system between infrastructure, environment and vehicles. The expand of emobility based on Electric Vehicles has been restricted by numerous shortcomings such as their driving range, the battery size, the dependence on charging stations and the time required for its charging.

  4. 3. Kilowatt Three-phase Rotary Transformer Design for Permanent Magnet DC Motor with On-rotor Drive System

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Ye Xu; [2016]
    Keywords : contactless energy transfer; transformer power loss; iron loss; iron loss model; rotary transformer; three-phase transformer; finite element method; COMSOL Multiphysics; electrical steel; electrical steel manufacturing process;

    Abstract : The aim of this thesis is to design a kilowatt three-phase step-down rotary transformer for a permanent magnet DC motor. The permanent magnet DC motor has an on-rotor drive system, and therefore requiring a power supply that can transfer power to its drive unit without mechanical contact. READ MORE
