Special Issue Information
Dear Colleagues,
The wide use of nonlinear loads, such as diode or thyristor front-end rectifiers and switching power supplies, causes the injection of high amounts of current harmonics in today’s distribution networks. These harmonics cause voltage distortion, additional losses in transformers and in line capacitors, and the malfunction of sensitive electronic equipment. Thus, harmonic restriction standards recommend limiting the harmonic currents injected into the mains by nonlinear loads.
Passive filters are very simple, low-cost, and high-efficiency solutions, but their performance strongly depends on the source impedance and can lead to unwanted resonance with the network.
The cost reduction and the increased reliability of power electronics has led to an increased interest for active filtering and hybrid filtering (passive and active). Active filtering is advantageous where a fast response to dynamic load changes is required. In addition, a digitally controlled APF represents a versatile power conditioning tool, since the different compensation tasks can be modified by changing the software of the digital controller.
This Special Issue aims at encouraging researchers to address the active and hybrid filter solutions to limit electric network distortion phenomena.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
