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 ...

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.

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 ...

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.

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.

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.

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

Design of LCL-filters with LCL resonance frequencies beyond the Nyquist frequency for grid-connected inverters

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
This paper proposes a novel LCL-filter design method and its current control for grid-connected converters. With the proposed design method, it is possible to set the resonance frequency of the LCL-filter to be higher than the Nyquist frequency, i.e. half of the system sampling frequency, and this observation is so far not discussed in the literature ...

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 ...
