Regions of Active Damping Control for LCL Filters

IEEE Transactions on Industry Applications, 2012
The control of a grid connected voltage source inverter (VSI) with an LCL filter is a very challenging task, since the LCL network causes a resonance phenomenon near to the control stability boundary. While many active damping methods have been proposed to overcome this issue, the role that PWM transport delay plays in the effectiveness of these ...

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 ...

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.

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.

Adaptive current control for grid-connected converters with LCL-filter

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
This paper presents a discrete-time adaptive current controller for grid-connected pulse width modulation voltage source converters with LCL filter. The main attribute of the proposed current controller is that, in steady state, the damping of the LCL resonance does not depend on the grid characteristic since the adaptive feedback gains ensure a ...

Design of LCL filter for wind power inverter

2010 World Non-Grid-Connected Wind Power and Energy Conference, 2010
An 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 ...

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.

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 ...
