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.

Spread Spectrum Modulation for LCL Filter Design
2019 20th International Symposium on Power Electronics (Ee), 2019The 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.

Magnetic Integration of LCL Filters
2017An 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.

Grid Impedance Estimation via Excitation of $LCL$-Filter Resonance
IEEE Transactions on Industry Applications, 2007Inverters 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.

Resonance Damping Methods of LCL Filter
2017The 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.

Design of LCL filter for wind power inverter
2010 World Non-Grid-Connected Wind Power and Energy Conference, 2010An LCL filter is more and more widely used in wind power inverters. However, it may easily result in instability due to resonance, which makes it difficult for stability control without damping. A voltage oriented control strategy under the dq synchronization reference frame is adopted based on the mathematical model of the three-phase inverter for ...

PWM rectifier based on LCL filter parameter optimisation
International Journal of Industrial and Systems Engineering, 2014In order to resolve the shortcomings of traditional single L-filter dynamic performance, LCL filter is introduced to PWM rectifier, which has a smaller inductance value and a good filtering effect. A new method PWM rectifier based on LCL filter parameter optimisation is proposed in this paper.

Controlled single-phase current source with LCL filter
2014 ELEKTRO, 2014This study proposes control algorithm for controlled single-phase current source. The power circuit of single-phase current source uses LCL type filter instead of a traditional L filter. The main advantage of LCL filter is lower current ripple, but it is necessary to use the advanced current control.
