Due to the wide spread of power electronics equipment in modern electrical systems, the increase of the harmonics disturbance in the ac mains currents has became a major concern due to the adverse effects on all equipment. This paper presents the analysis and simulation using Matlab Simulink of a three-phase four wire neutral clamped active power filter (APF) compensating the harmonics and reac...

Nonlinear and unbalance loads in three phase networks create harmonics and losses. Active and passive filters are used for elimination or reduction of these effects. Passive filters have some limitations. For example, they are designed only for a specific frequency and they may cause to resonance in the network at the point of common coupling. The other drawback of a passive filter is that the ...

This paper investigates mitigation of current harmonics using different configuration of cascaded multilevel inverter based shunt hybrid active power filter (SHAPF) and to improve power quality of the system. The main objective of this paper is to develop and analyze the compensation characteristics of cascaded multilevel inverter based shunt hybrid active power filter by employing indirect cur...

This paper presents a new control scheme of voltage source active filter (AF) which compensates simultaneously the harmonics and reactive power of non-linear loads. The reference compensating currents are estimated from computed reference supply currents and sensed load currents. Reference supply currents are estimated using active power of the load and the AF. A hysteresis or carrier based PWM...

The proposed DVSI scheme consists of two ...

Frequency-modulated continuous-wave (FMCW) radars necessitate fast frequency modulation. However, finite loop bandwidth of a phase-locked (PLL) limits the accuracy This paper proposes phase compensation (PC) technique to address this limitation. The synthesizer PLL with PC realizes and precise triangular chirp modulation by adding compensating square wave before integral path filter. is designe...

The paper studies the road-constrained vehicle tracking problem employing the multiple-model particle filtering framework. It introduces an approach which enables for a more efficient particle use within the multimodel structure of the tracker; rather than allocating the particles to the various modes of operation using fixed mode probabilities, it proposes to allocate the particles freely acco...

In this paper a hearing aid concept working in subbands is presented. Consideration is given to the compensator for recruitment of loudness and the acoustic feedback cancellation. In addition, a step-size control for fast tracking and a constant error level with non-stationary input signals is presented. The feedback canceler is adapted to the feedback path in the transform domain using a power...
