Research on the Hybrid Active Power Filter

Advanced Materials Research, 2011
Passive power filter (PF) has problems that source impedance may strongly affect the filtering characteristics and cause system resonance in power system applications. Hybrid active power filter (HAPF) can improve the performance of passive filter and realize harmonics restraint and reactive power compensation in big power situation. In this paper, the

Active power filter with hybrid energy storage

20th Annual IEEE Power Electronics Specialists Conference, 1991
An active power filter that uses an impressed current converter and an inductive-capacitive energy storage circuit is presented. This storage includes a switching section to interface the inductive and capacitive element. This solution allows independent choice of the converter configuration and of the type of storage system which, in this particular ...

A novel series hybrid active power filter

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
A novel series hybrid active power filter is proposed. Compared with the conventional series active power filter (SAPF) or the series hybrid active power filter, its active part only needs to suppress some low order harmonics. So the capacity factor of the inverter's DC voltage is improved a lot and the power rating of the active part decreases ...

Simulation Study on Hybrid Active Power Filter

2012 Fifth International Conference on Intelligent Computation Technology and Automation, 2012
A parallel hybrid simulation model of active power filter is established by using MATLAB/Simulink tool, and simulated parameter settings and simulation analysis of each link of the system are done in this paper. The results of the simulation proved that the hybrid active filter can suppress harmonics well and compensate reactive power of the power ...

Active impedance‐based single‐phase hybrid active power filter

IEEJ Transactions on Electrical and Electronic Engineering, 2019
This article presents a single‐phase hybrid active power filter (1pSHAPF) containing a small rated active power filter connected in series with a single‐tuned inductive‐capacitive (LC) passive filter. Single‐phase nonlinear loads are increasing alarmingly in the distribution system.

Selective Power Management Control for Hybrid Active Power Filter

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
Compared with traditional active power filter (APF), the hybrid active power filter (HAPF) can be considered as a good tradeoff between compensation range and active inverter rating. However, the load harmonic and reactive power is easily beyond the compensation range of HAPF, the HAPF with the conventional control methods cannot provide satisfactory ...

Hybrid series active power filter for mitigating power quality problems

2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017
This paper presents various power quality problems and its mitigation through a hybrid series active power filter. Series filters have less attention in the power quality area due to its high cost of compensation, bulky transformers etc. Even though hybrid series active power filters are used in three phase system it is less utilized in single phase ...
