In silicon on chip technology demands high performance and low power Very Large Scale Integrated Circuit (VLSI) digital signal processing (DSP) systems. The aim of this paper explores the power consumption technique for the architecture of Finite Impulse Response (FIR) adaptive filter. An adaptive FIR filter with Block Least Mean Square (BLMS) algorithm was developed to reduce the power. Distri...

We briefly introduce the source and harm of aircraft grid harmonic and summarise the common methods of harmonic reduction, such as passive filter, multi-pulse rectifier, power factor correction and active power filter. Then we introduce the disadvantages of the above methods, analyse the application status, advantages and deficiencies of active power filter in aircraft grid harmonic reduction, ...

This paper proposes a new adaptive filter for wind generators that combines instantaneous reactive power compensation technology and current prediction controller, and therefore this system is characterized by low harmonic distortion, high power factor, and small DC-link voltage variations during load disturbances. The performance of the system was first simulated using MATLAB/Simulink, and the...

The increasing use of power electronic based loads (adjustable speed drives, switch modern power supplies, etc) to improve system efficiency and controllability is increasing concern for harmonic distortion levels in end use facilities and on overall power system. The Active Power Filter uses power electronic switching to generate harmonic currents that cancel harmonic content from non – linear...

This paper presents a grid connected photovoltaic system, which acts as both power generator and active power filter (APF), based on Flying Capacitor Multicell (FCM) converter. Increase in the number of output voltage levels, natural self-balancing of flying capacitors and dc link voltage and lower power rating of components are the main futures of FCM converter compared with conventional multi...
