Experimental Characterization of Reference Currents for Harmonic Compensation: Case of the TLC Hybrid Filter

Abstract

This article proposes an experimental characterization of the currents of inductive, capacitive and linear loads in order to obtain an extraction of the reference currents for harmonic compensation by the use of an adaptive hybrid filter TLC which offers advantages such as the reduction of switching losses during the injection of currents into the network, limitation of resonance problems and above all low energy consumption at the DC bus level, thus allowing us to obtain standardized results from 105V. Compared to existing models in the literature which require 600V for the same performance. This article therefore simultaneously offers two contributions, the first being articulated around the advantages offered by the TLC hybrid architecture of our prototype and the second is focused on the experimental characterization of the currents of the different loads. An implementation of the H-infinity command is therefore applied to the TLC hybrid filter in the first section followed by an experimental characterization using a test bench in the second section. The results obtained with this algorithm give us THDs conforming to the IEEE 519-2014 standard and which are very significant when compared to the results obtained with other robust and stochastic control algorithms taken under the same conditions and applicable to systems intelligent electrics with API-Siemens modules.
