This paper presents a filter scheme composed by passive and series active power filters specially designed to compensate fundamental reactive power (with passive filters) and current harmonics (combination of passive and ...

Measurements on a passive optical fibre tunable filter are presented. The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a coupler. The novel ...

This paper presents possible selective current compensation strategies based on the Conservative Power Theory (CPT). This recently proposed theory, introduces the concept of complex power conservation under non-sinusoidal ...

This paper presents a design method for passive filters used to compensate power factor and current harmonics generated by high power cycloconverter drives. The paper includes the analysis of different passive filter ...

This paper presents the performance analysis of a hybrid filter composed of passive and active filters connected in series. The analysis is done by evaluating the influence of passive filter parameters variations and the ...

This paper presents the study of dynamic interactions between passive filters and high power cycloconverters drives. The dynamic interaction considers the impact of connection and disconnection of passive filters operating ...

An industrial controller, specifically designed for two- and three-level converters, was adapted to work on an asymmetrical nine-level active power filter (APF). The controller is now able to make all required tasks for ...

This work elaborates a study of the theory, simulation and solution of some cases considering the use of active and passive analog filters, aiming to complement the study in the electronics area of the Electrical Engineering ...
