  • We present in this paper a control method of a novel hybrid parallel active power filter (HPAPF) used for harmonic currents elimination and reactive power compensation in the power system for threephase variable frequency drives (VFDs). The HPAPF configuration is built from two basically filter components including harmonics tuned passive filter and active power electronics filter.

  • This calculation is done because of the emergence of harmonics on a 3-phase induction motor that has exceeded the standard limit, so it must reduce the harmonics. Moreover, disturbances that occur, such as torsion vibrations caused by the interaction of the fundamental harmonic magnetic field, causing higher noise.

  • To mitigate the harmonic problems in industrial power system, the simple way is to use shunt passive filters. This paper presents the effect of compensation and detuning of single tuned shunt passive filter on harmonics of industrial distribution system. The three phase power system and single tuned passive filter is designed, modeled and simulated in MATLAB by using the actual data collected from industry is used.

  • This filter uses bearings only measurements to estimate the target state in passive target tracking scenario. This work combines the MGEKF and the iteration method. The filter utilizes the updated state to re-linearize the measurement equation. Then the proposed work is tested in a two dimensional scenario. The simulation study compares the IMGEKF and some other filters to show the improvement.

  • Over many years, RF-MEMS have been a hot topic in research at the technology and device level. In particular, various kinds of mechanical Si-MEMS resonators and piezoelectric BAW (bulk acoustic wave) resonators have been developed. The BAW technology has made its way to commercial products for passive RF filters, in particular for duplexers in RF transceiver front ends for cellular communications. Beyond their use in filters, micromachined resonators can also be used in conjunction with active devices in innovative circuits and architectures.

  • ACTIVE FILTER DESIGN WITH NOMINAL ERROR Although electric wave filters have been used for over a century since Marconi’s radio experiments, the identification of stable and ideally terminated filter networks has occurred only during the past 35 years. Filtering at the lower instrumentation frequencies has always been a problem with passive filters because the required L and C values are larger and inductor losses appreciable.
