    Nyckelord :;

    Sammanfattning : Radiofrekvens baserad teknik har utlöst ett stort område inom forskning och utveckling. Denna avhandling arbete bygger på RF krafttransistorer och deras sedvänjor i olika tillämpningar. Traditionellt har RF-transistorer som används i applikationer basstationer. LÄS MER

  5. 4. Design of Harmonic Filters for Renewable Energy Applications

    Magister-uppsats, Institutionen för kultur, energi och miljö

    Författare :Bhunesh Kumar; [2011]
    Nyckelord :Digital Filter; Impulse Response; Wave Digital Filter; Circulator-Tree WAVE Digital Filter; Harmonics Filter; Renewable energy Filter; Wind Energy Filter; Butterworth; Chebyshev and Cauer filters; Low-pass; High-pass and Band-pass filters;

    Sammanfattning : Harmonics are created by non-linear devices connected to the power system. Power system harmonics are multiples of the fundamental power system frequency and these harmonic frequencies can create distorted voltages and currents. Distortion of voltages and currents can affect the power system adversely causing power quality problems. LÄS MER

  7. 5. Studies on Circulator-Tree Wave Digital Filters

    Master-uppsats, Institutionen för systemteknik

    Författare :Bhunesh Kumar; Naeem Ahmad; [2009]
    Nyckelord :Filter; Impulse response; attenuation; series adaptor; parallel adaptor; adaptor coefficient; circulator-tree structure; wavedigital filter;

    Sammanfattning : A wave digital filter is derived from an analog filter, which is realized as classical doubly resistively terminated reactancefilters. Perfectly designed wave digital filters express good dynamic signal range, low roundoff noise and excellent stabilitycharacteristics with respect to nonlinearity which are produced due to finite wordlength effects.
