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

Research on New Hybrid Active Power Filter

Advanced Materials Research, 2011
A new hybrid active power filter (NHAPF) and its corresponding controlling method are proposed in the paper, which can be applied in high voltage system. The topology structure of NHAPF is given and its compensating principle is described. The corresponding controlling method is a power direct control, which need not the lower pass filter and improve ...

A Novel Hybrid Active Power Filter with Multi-Coupled Coils

Electronics (Switzerland), 2021
This paper proposes a hybrid active power filter (HAPF) with multi-coupled coils, applied to a medium- and high-voltage power grid. The passive filter of the proposed HAPF adopts the structure of multi-coupled coils to compress the traditional multiple ...

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 ...

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
