  4. 18. CALLUM Linear Transmitter - Architecture and Circuit Analysis

    Författare :Roland Strandberg; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; loop time delay; modulation negative feedback; spectral emissions; baseband model; CALLUM; Linear transmitter architecture; power amplifier linearization;

    Sammanfattning : This doctoral dissertation presents a study of linear radio transmitters based on the combined analog locked loop universal modulator (CALLUM) approach. Linear architectures such as CALLUM are very attractive for power-efficient operations, since they have no fundamental limitations prohibiting a 100% efficiency for all envelope levels, without sacrificing the potential of a linear transmission.

  5. 19. Co-Simulation of Coupled Electromagnetic and Nonlinear Circuit Problems using the Partial Element Equivalent Circuit Method

    Författare :Sohrab Safavi; Wil Schilders; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Co-simulation of coupled electromagnetic (EM) structures and linear/nonlinear circuits has become a major demand in today's engineering. In many disciplines such as antenna engineering, microwave circuit design, electromagnetic compatibility (EMC), and even fairly low-frequency power electronic systems, simulation techniques capable of incorporating both EM structures and lumped circuit elements have become a necessity.

  7. 20. Demagnetization and Fault Simulations of Permanent Magnet Generators

    Författare :Stefan Sjökvist; Sandra Eriksson; Sami Ruoho; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demagnetization; Permanent magnet; Finite Element Method; Synchronous generators; Wind power; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : Permanent magnets are today widely used in electrical machines of all sorts. With their increase in popularity, the amount of research has increased as well. In the wind power project at Uppsala University permanent magnet synchronous generators have been studied for over a decade. LÄS MER
