  1. 1. Conductive interferences from multiple EC-motor installation : To measure and mitigate harmonics

    University essay from Uppsala universitet/Signaler och system

    Author : Victor Aitman; [2022]
    Keywords : harmonics; interharmonics; harmonic-mitigation; electromagnetic compability; EMC; övertoner; EC-motorer; störningar; övertonsreducering; elektromagnetiskt kompabilitet; EMC;

    Abstract : Products produced by a Swedish company are requested to be investigated regarding their harmonic and inter-harmonic currents injected into the public supply system to comply with the Swedish standard SS-EN IEC 61000-3-2, Electromagnetic compatibility (EMC).    On behalf of Systemair Sweden AB, this bachelor thesis aims firstly to investigate if their product, PAFEC 4225 WH (Air Curtain), complies with standard SS-EN IEC 61000-3-2, and if not, what measures should be taken; and secondly to develop a low-cost instrument for the measurement of harmonics and inter-harmonics according to standard IEC 61000-4-7 related to the requirements on equipment used in standard SS-EN IEC 61000-3-2.

  3. 2. Real-time image based lighting with streaming HDR-light probe sequences

    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : Saghi Hajisharif; [2012]
    Keywords : ;

    Abstract : This work presents a framework for shading of virtual objects using high dynamic range (HDR) light probe sequences in real-time. The method is based on using HDR environment map of the scene which is captured in an on-line process by HDR video camera as light probes [32]. READ MORE

  5. 4. Implementation and Evaluation of a RF Receiver Architecture Using an Undersampling Track-and-Hold Circuit

    University essay from Institutionen för systemteknik

    Author : Magnus Dahlbäck; [2003]
    Keywords : Electronics; RF; track-and-hold; undersampling; receiver; noise folding; harmonics aliasing; Elektronik;

    Abstract : Today's radio frequency receivers for digital wireless communication are getting more and more complex. A single receiver unit should support multiple bands, have a wide bandwidth, be flexible and show good performance. To fulfil these requirements, new receiver architectures have to be developed and used. READ MORE
