Backstepping control for active power filter with LCL filter

2nd IET Renewable Power Generation Conference (RPG 2013), 2013
Active power filters are widely applied in power system to deal with distorted currents caused by nonlinear loads. As the active power filter (APF) with LCL filter is a serious nonlinear system, conventional control methods cannot have satisfactory performances. A nonlinear control method, backstepping control for active power filter with LCL filter is

Control of LCL filter based voltage source converter

Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010
In this paper, the control of Voltage source converter which consists of six IGBT power switches is realized. Grid connection of VSC is provided through LCL filter and sinusoidal pulse width modulation (SPWM) technique which has 9 kHz switching frequency, is used for switching.

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 ...

Filter-Based Active Damping of Voltage Source Converters With $LCL$ Filter

IEEE Transactions on Industrial Electronics, 2011
Pulsewidth modulation (PWM) voltage source converters are becoming a popular interface to the power grid for many applications. Hence, issues related to the reduction of PWM harmonics injection in the power grid are becoming more relevant. The use of high-order filters like LCL filters is a standard solution to provide the proper attenuation of PWM ...

Comparative analysis of the selective resonant LCL and LCL plus trap filters

2014 International Conference on Optimization of Electrical and Electronic Equipment (OPTIM), 2014
In this paper two promising LCL based filter topologies are evaluated against the well-known LCL with a damping resistor. The filters are designed for high power applications where the frequency modulation index is relatively low. The first topology is the selective resonant LCL filter which aim is to minimize the damping losses by bypassing the ...

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.
