LMS Algorithm Based Fundamental Current Detection for Shunt Hybrid Filter

R. Sriranjani and S. Jayalalitha

Abstract:
An adaptive control technique is used to extract the fundamental current for the active filter. The Shunt Hybrid Filter (SHF) comprises passive filter (resonant filter) and active filter. The passive filter is tuned to suppress dominant harmonics and the active filter is tuned to reduce harmonics and reactive power of the supply mains. The Least mean Square (LMS) algorithm is used for implementing Hysteresis current control. The dc bus voltage is regulated using Proportional-Integral controller which improves the dynamic characteristics of SHF. The Shunt Hybrid filter with the dc bus voltage control is analysed by the MATLAB simulink and the results are compared.
