Special Issue Information
Dear Colleagues,
Symmetry and asymmetry are fundamental concepts in the modeling, design, and control of power electronic converters and energy conversion systems. Symmetric structures—such as balanced multi-phase converters, symmetric modulation patterns, and harmonic symmetry—enable simplified analysis, improved efficiency, reduced distortion, and enhanced robustness. However, real-world operation is inevitably affected by asymmetries originating from component tolerances, parameter drift and aging, unbalanced loads, grid voltage unbalance, faults, unequal thermal stress, and intermittent renewable generation. These asymmetries can strongly impact converter stability, power quality, reliability, and protection, and they motivate advanced modeling, diagnostics, and control strategies.
This Special Issue aims to provide a focused forum for theoretical and applied contributions addressing how symmetry principles are exploited, broken, detected, and compensated for in modern power electronics. The theme fits within the scope of the journal Symmetry in that it emphasizes invariances and symmetry-related properties in system dynamics, modulation, harmonic content, stability, and fault behavior.
We welcome original research articles, review papers, and case studies on converter topologies (including multilevel and grid-connected converters), modulation and harmonic symmetry, operation under unbalanced and faulty conditions, symmetry-based modeling and stability assessment, fault diagnosis, and fault-tolerant control for renewable energy and smart grid applications.
We look forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.
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. Symmetry is an international peer-reviewed open access monthly 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 2400 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.
