Study of the operation of the output filter of a single-phase series active power filter [PDF]
International Journal of Power Electronics and Drive Systems (IJPEDS), 2021 In the article is presented a single-phase series active power filter (SFSAPF) designed to compensate the total harmonic distortion (THD) factor of the supply network voltage. Particular attention is paid to the work of the output capacitor of the passive filter, and dependencies for the design of the filter at hysteresis voltage control are presented.

Adaptive Filter and Resonant Controller Applied to Hybrid Series Active Power Filter [PDF]
, 2012 This paper proposes a control strategy for Hybrid Active Series Power Filter (HASPF) based on a P+Resonant compensator. The proposed control uses Adaptive Notch Filter to isolate the harmonic content of the source current and a P+Resonant regulator to calculate the harmonic voltage signal necessary to properly tune the hybrid branch.

Stability Analysis of the Series-In Series Hybrid Active Power Filter
Applied Mechanics and Materials, 2011 For the important characteristic of the system stability, a state-space averaging model of the series-in series hybrid active power filter (SHAPF) is constructed to analyze its system stability by traditional control strategy taking into account the effect of the time delay in the digital control system, inverter, low pass filter and second-order ...

Digital simulation of a hybrid active filter-an active filter in series with a shunt passive filter [PDF]
Power Quality '98, 2002 Active filters have long been in use for the filtering of power system load harmonics. In this paper, the digital simulation results of a hybrid active power filter system for a rectifier load are presented. The active filter is used for filtering higher order harmonics as the dominant harmonics are filtered by the passive filter.

A Combined Series Active Filter and Passive Filters for Harmonics, Unbalances and Flicker Compensation [PDF]
2007 International Conference on Power Engineering, Energy and Electrical Drives, 2007 This paper describes a combined operation involving a series active filter and shunt passive filters for three-phase three-wire systems. The series active filter is able to minimize Power Quality problems like unbalances, harmonics and flicker observed at the system voltages.

A Series Active Filter Controlled by Personal Computer.
RE&PQJ, 2023 This paper describes work that is being done in the design and implementation of a series active power filter for electrical power quality purposes. This type of filter is able to compensate for the following voltage related problems in the power grid: short blackouts for a few cycles, voltage distortion due to harmonics on a repetitive basis, voltage ...
