2. 1. Electromagnetic Modeling with Complex Dielectrics : A Partial Element Equivalent Circuit Approach

   Author : Andreas Hartman; Jonas Ekman; Jerker Delsing; Frank Gronwald; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

   Abstract : Wireless communication systems have become an integral part of many complex systems in diverse areas of society, for the exchange of data in business and industrial settings. With the advent of Internet of Things (IoT) and wireless sensor network architectures, the tighter demands on interoperability between different devices are putting heavy requirements their ability to exchange data wirelessly among them reliably.

5. 3. Charge Sampling Circuits and A/D Converters - Theory and Experiments

   Author : Gang Xu; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

   Abstract : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. READ MORE

6. 4. High Frequency (MHz) Planar Transformers for Next Generation Switch Mode Power Supplies

   Author : Radhika Ambatipudi; Kent Bertilsson; Bengt Oelmann; Jesus Doval Gandoy; Hans-Peter Nee; Torbjörn Thiringer; Göran Thungström; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Planar Magnetics; DC-DC Converters; Switch Mode Power Supplies; MHz Frequency Region;

   Abstract : Increasing the power density of power electronic converters while reducing or maintaining the same cost, offers a higher potential to meet the current trend inrelation to various power electronic applications. High power density converters can be achieved by increasing the switching frequency, due to which the bulkiest parts, such as transformer, inductors and the capacitor's size in the convertercircuit can be drastically reduced.

7. 5. Main-circuit considerations of power coverters for integral motors

   Author : Karsten Kretschmar; Hans-Peter Nee; Johan Walter; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Permanent magnet integral motor; Small DC link; Elektronik; Electronics; Elektronik;

   Abstract : This thesis deals with different converter topologies for a 15kW permanent magnet (PM) integral motor. An integral motor combines the motor and the power electronics in one unit. The main objective is to find suitable converter alternatives for an integral motor. READ MORE
