Simulation and comparison between hybrid active power filter and shunt active power filter

2015 International Conference on Electrical, Electronics, Signals, Communication and Optimization (EESCO), 2015
The shunt active power filters (SAPFs) and hybrid active power filter (HAPF) is used for practical solution to solve the electric power quality, (EPQ) issues. The emerging power-electronic devices and the new developments in digital signal processing (DSP), have made possible its practical use. The active power filters can compensate the nonlinear load

Improved shunt active power filters

2008 International School on Nonsinusoidal Currents and Compensation, 2008
This paper describes a shunt active power filters (APF) with improved dynamic performance. When the value of load current changes rapidly, the APF transient response is too slow, the line current suffers from dynamic distortion. This distortion causes an increase of harmonic content in the line current, which is dependent on a time constant.

Better performance for shunt active power filters

2011 International Conference on Clean Electrical Power (ICCEP), 2011
This paper proposes a time domain harmonic detection technique which is an improved a-b-c reference frame formula based upon the p-q theory with a positive sequence detector to solve the problem of bad performance of shunt active power filters (SAPF) under non-ideal mains.

The application of DSP in shunt active power filter

2011 Second International Conference on Mechanic Automation and Control Engineering, 2011
DSP chips are widely used in automatic control, mage processing, communications technology and other fields. In this paper, the application of DSP in shunt active power filter (SAPF) was discussed. Taken a DSP as the core controller, the experimental study on the SAPF was carried out, and the results of experiment were analyzed.

Robust DPC-SVM control strategy for shunt active power filter based on H∞ regulators

, 2020
This paper proposes an improved direct power control (DPC) strategy for shunt active power filter (SAPF). The conventional DPC control suffers from variable switching frequency and high-power ripples due to hysteresis comparators used.

Real-Time Implementation of Shunt Active Power Filter With Reduced Sensors

IEEE transactions on industry applications, 2020
Performance of shunt active power filter (SAPF) depends on the effectiveness of control strategy, which requires information about voltages and currents obtained from sensors. Faults in these sensors cause SAPF to aggravate power quality problems instead

A novel active power filter with shunt transformer

2009 International Conference on Electrical Machines and Systems, 2009
In the paper, a novel active power filter with a shunt transformer and an inverter is proposed. A transformer is chosen and its primary winding is connected in parallel with harmonic source, the primary fundamental voltage is detected and functions as the given signal.

Energy controlled shunt active power filters [PDF]

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2007
PurposeShunt active power filters are used to decrease or almost eliminate non‐active currents flowing through the supply source. Numerous control methods of active filters have been proposed in many papers. The aim of this paper is to demonstrate a simple but very effective method of obtaining the compensated load active current.Design/methodology ...

Robust Repetitive Control Design for a Three-Phase Four Wire Shunt Active Power Filter

IEEE Transactions on Industrial Informatics, 2019
This paper presents a discrete repetitive control technique for three-phase four wire (3P4W) shunt active power filter (SAPF). Generally, the control design for power electronics devices involves two control loops: slow acting outer voltage loop and fast
