1. 16. 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

3. 17. Textile Integrated Induction : Investigation of Textile Inductors for Wireless Power Transfer

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Malin Yring; [2016]
   Keywords : Textile inductors; induction; wireless power transfer; WPT wireless energy transfer; WET; wireless powering; wireless charging; magnetic resonant coupling; resonant coupling; e-textiles; smart textiles;

   Abstract : This research has its basis in developments within the field of inductive powering and wireless power transfer, WPT, and more specifically one the branch within this field, which is called magnetic resonance coupling. This principle enables efficient power transfer from a transmitting unit to a receiving unit at a distance of some times the unit diameter. READ MORE

4. 18. Investigation and Study of Crosstalk

   University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

   Author : Krishna Prasad Rao Pasupuleti; [2015]
   Keywords : Överhörning; Crosstalk; Electricfield coupling; magneticfield coupling; capacitiv coupling; kapacitiv koppling; Inductive coupling; induktiv koppling.;

   Abstract : Crosstalk is defined as an unwanted coupling between the conductors. By this it is meant that signals from one of the signal conductors (a generator in this case) are coupled to another signal conductor (receptor), or conductors (receptors), depending on the number of conductors in the vicinity of the generator.

5. 19. Design of Inductive Coupling for Powering andCommunication of Implantable Medical Devices

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Andreas Svensson; [2012]
   Keywords : ;

   Abstract : Technological advances over the years have made it possible to reduce the size and power consumption of electronics. This has led to significant advances for biomedical sensors. It is now possible to reduce the size enough to create implantable sensors. This type of sensors can for instance be used to measure the glucose level of diabetes patients. READ MORE

6. 20. High Level Ultra Low Power Transmitters for the MICS Standard

   University essay from Elektroniska komponenter

   Author : Per Eidenvall; Nils Gran; [2010]
   Keywords : Ultra Low Power; MICS; PSK; QPSK; Radio Transmitter; QPSK Modulator;

   Abstract : Today, medical implants such as cardiac pacemakers, neurostimulators, hearing aids anddrug delivery systems are increasinglymore important and frequently used in the health caresystem. This type of devices have historically used inductive coupling as communicationmedium. READ MORE
