Special Issue Information
Dear Colleagues:
The innovative and efficient design of electrical insulation in power-electronic-controlled machines and devices is critical for enhancing their reliability and extending their operational lifetime. The inclusion of power electronics into the power system environment results in repetitive voltage impulses, harmonics from switching systems, and slow/fast rising voltage transients. These factors are known to introduce additional electro-thermal stresses, which results in significantly accelerating the aging process of electrical insulation. This accelerated aging occurs at a rate that is unpredictable based on existing life models. As a result, the traditional methods of predicting insulation lifespan and reliability are becoming less effective, necessitating new approaches and advanced diagnostic techniques to manage and mitigate these emerging stresses.
Worldwide, researchers are invited to submit their original work relevant to the improvement of reliability and performance of power-electronic-controlled devices in electrical grids, which includes, but is not limited to, the implementation of advanced insulation materials and technologies, establishing robust criteria for aging evaluation and predicting insulation lifespan, condition monitoring of insulation systems, partial discharges, and fault detection in electric machines such as rotating machines and transformers.

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. Machines 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.
