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.

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.

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 ...

Robust Quasi-Predictive Control of $LCL$-Filtered Grid Converters

IEEE Transactions on Power Electronics, 2020
This paper proposes a new control strategy for grid-connected LCL-filtered voltage source converters (VSCs). It is realized by cascading a proportional-resonant (PR) controller, which regulates the grid-side current, and a finite-set model predictive controller (FS-MPC), which is responsible for controlling the filter's capacitor voltage and active ...

Regenerative AC electronic load with LCL filter

2012 10th IEEE/IAS International Conference on Industry Applications, 2012
This article present the design and implementation of a regenerative AC electronic load with LCL filter. The electronic load is composed by a current controlled rectifier, which drains from the equipment under test (EUT) the desired current profile, and a current controlled inverter connected to the grid, which is responsible for power regenerating ...

Three-Phase PFC Converter with Reconfigurable LCL Filter

2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021
In this paper, a novel three-phase PFC topology with a reconfigurable LCL filter is proposed with not necessary any additional grid-side inductors. The reconfigurable LCL filter consists of the original converter-side inductors and filter capacitors and a group of additional low-frequency bidirectional switches.

Spread Spectrum Modulation for LCL Filter Design

2019 20th International Symposium on Power Electronics (Ee), 2019
The LCL filter is often the bulkiest component in grid-tied converters, which is designed to satisfy the grid harmonic standards such as IEEE519. To reduce the filter requirement, application of the spread spectrum modulation (SSM) to LCL filter design is investigated in this paper.

Grid Impedance Estimation via Excitation of $LCL$-Filter Resonance

IEEE Transactions on Industry Applications, 2007
Inverters adopted in distributed power generation, active filter, and uninterruptible power supply are often connected to the grid through an inductance-capacitor-inductance (LCL) filter. The impedance of the LCL filter has a typical frequency characteristic with a resonance peak.
