Solid State Transformers

Dear Colleagues,

Transformers have played a critical role in the development of the current power system for more than a century and today represent a mature technology and an established market with multiple vendors. Power electronics are becoming more prevalent in the modern power system and have begun to have a substantial impact. They enable a great range of possibilities such as microgrids of multiple scale, bidirectional and multi-directional power systems, and combined ac/dc power flows.

Solid-state transformers (SSTs), also referred to as Power Electronics Transformers (PETs), have emerged in the effort to address many of these applications. They include power electronics stages across different voltage levels typically connected through a medium or high frequency transformer. SSTs are gradually moving from the research to the development and application stage and expanding from niche to more mainstream applications in smart grids, with the aim of becoming flexible assets for DSOs and TSOs in the future.

Our goal in this Special Issue is to address timely and topical research findings as well as operational experience in SSTs/PETs. We welcome high-quality, original works on topics such as, but not limited to, the following:

• Power electronics converter topologies for solid-state transformer applications.
• The control and operation of solid-state transformers.
• Medium and high frequency, and medium- and high-power transformers.
• Applications of solid-state transformers.
• New semiconductor devices in SST transformers.
• The reliability of SSTs.
• Real-time modelling and simulation of SSTs.
• The development and testing of experimental prototypes.

All submitted manuscripts will be subject to a thorough peer-review and editorial process.

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.
