A Novel (DDCC-SFG)-Based Systematic Design Technique of Active Filters [PDF]

open access: yesRadioengineering, 2013
This paper proposes a novel idea for the synthesis of active filters that is based on the use of signal-flow graph (SFG) stamps of differential difference current conveyors (DDCCs).

Analysis of Amoeba Active Contours [PDF]

open access: yes, 2014
Subject of this paper is the theoretical analysis of structure-adaptive median filter algorithms that approximate curvature-based PDEs for image filtering and segmentation. These so-called morphological amoeba filters are based on a concept introduced by

Digital Current-Control Schemes [PDF]

open access: yes, 2009
The paper is about comparing the performance of digital signal processor-based current controllers for three-phase active power filters. The wide use of nonlinear loads, such as front-end rectifiers connected to the power distribution systems for dc ...

Harmonics and unbalanced load compensation by a modular multilevel cascaded converter active power conditioner

open access: yesThe Journal of Engineering, 2019
This paper presents a novel control scheme for a modular multilevel cascaded converter (MMCC) functioning as an active power conditioner (APC) to control the reactive power, eliminate the current harmonics, and compensate unbalanced load current ...

Single-chip inverter for active filters [PDF]

open access: yes, 2002
Generally inverter-based active filters, which employ pulse-width-modulated (PWM) techniques, use microprocessors for overall control and discrete logic for the generation of switching patterns.
