Design of LCL Filter

2017
As the interface between renewable energy power generation system and the power grid, the grid-connected inverter is used to convert the dc power to the high-quality ac power and feed it into the power grid. In the grid-connected inverter, a filter is needed as the interface between the inverter and the power grid.

LCL-Filter Dimensionierung für Vierleiter-Gleichspannungsstromrichter mit Akitv-Filter Funktionalität

2022
Gleichspannungsstromrichter (kurz: Stromrichter) halten seit geraumer Zeit verstärkt Einzug in das Energieversorgungsnetz. Allen gemein ist die Wandlung von elektrischer Energie aus einem Gleichspannungszwischenkreis hin zu einer Wechselspannung mit Netzfrequenz.

Magnetic Integration of LCL Filters

2017
An LCL filter has two individual inductors. In order to reduce the volume of magnetic components, magnetic integration of these two inductors is introduced in this chapter. First, the integration method of the two inductors of an LCL filter is proposed, and the magnetic circuit model of integrated inductors is built.

Online LCL filter compensation using embedded FRA

2014 IEEE Applied Power Electronics Conference and Exposition - APEC 2014, 2014
LCL filter control design is challenging because of presence of a resonant pole in the LCL filter transfer function. This paper presents a guideline for LCL filter design, which are often used in grid connected applications, with compensation based on complex poles and zeros.

A Robust Controller for a Grid-Tied Inverter Connected Through an LCL Filter

IEEE Journal of Emerging and Selected Topics in Industrial Electronics, 2021
This article presents a control strategy for three-phase inverters connected to grids through an LCL output filter. For this topology, it is known that when output current and capacitor current are fed back through certain optimal gains, the system is ...

Resonance Damping Methods of LCL Filter

2017
The control challenges of LCL-type grid-connected inverter arise from the resonance problem. At the resonance frequency, the LCL filter resonance causes a sharp phase step down of −180° with a high resonance peak. This resonance peak would easily lead to system instability and should be damped.

Reduced-Order Extended Observer and Correction Discretization Method for High-Speed Permanent Magnet Synchronous Motor With LCL Filter

IEEE Journal of Emerging and Selected Topics in Power Electronics
The forward Euler method is well known for its simplicity and ease of implementation in permanent magnet synchronous motor (PMSM) controls. However, it introduces significant errors, which become more severe when establishing the discrete-time model of a

Three-Phase Transformerless PV Inverter With Reconfigurable LCL Filter and Reactive Power Capability

IEEE transactions on power electronics
Constructing LCL filter with only three inductors is made possible by a topology called the reconfigurable filter in three-phase converters, in which the filter is reconfigured six times during the ac line cycle.

Research of Hybrid Rectifier with LCL Filter

2018 IEEE International Conference of Safety Produce Informatization (IICSPI), 2018
In order to restrain the current ripple in grid side of hybrid rectifier and the obvious current distortion caused by the current mutation in grid side of Vienna rectifier, an improved method that replace the L filter in gird side of Vienna rectifier and single switch three-phase boost rectifier (SSTPBR) with LCL filter is proposed in this paper ...
