Analysis and Design of LCL-filter in Shunt Active Power Filter
摘要
Abstract
Shunt active power filter (APF) needs wide compensation range and few switching harmonic components.LCL-filter is suitable for APF because of it's good characteristics of amplification in low frequency and attenuation in high frequency.However,LCL-filter is a three-order system causing complex design and oscillation problem at resonance frequency.Present studies analyze the LCL-filter mainly by simulations via MATLAB without giving formulation.This paper deduces a transfer function in S domain of LCL filter with damping resistances,and decomposes the function into several typical systems to analyze the influence of each parameter variation of LCL-filter on the performance of system.Simulation and experiment validate the correctness of the proposed method.关键词
