Design of LCL-Filter with Active Damping for Active Power Filter

Applied Mechanics and Materials, 2013
In this paper, the influence of gird-side and inverter-side inductance on LCL-filter performance is studied. The design method of LCL-filter applied in three-phase shunt active power filter (SAPF) is proposed. An active damping strategy using the current feedback of the filter capacitor is adopted to suppress the resonance.

Grid Impedance Estimation by Measuring Only the Current Injected to the Grid by a VSI With $LCL$ Filter

IEEE transactions on industrial electronics (1982. Print), 2021
A strategy for grid impedance estimation is proposed in this article. The strategy is based on the use of an observer suitable to implement the control and synchronization of a voltage-source inverter with an $LCL$ filter, by measuring only the current ...

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.

Applying an LCL-filter to a four-wire active power filter

2006 37th IEEE Power Electronics Specialists Conference, 2006
Especially in the case of voltage source shunt four-wire active power filters, the switching frequency current ripple is a significant problem and cannot be completely suppressed with an L-filter without impairing the harmonic filtering performance of the system. An LCL-filter is a third-order low-pass filter, which is commonly used with PWM rectifiers
