Applications of High-Efficiency Converters

Dear Colleagues,

In the days of the first ever global energy crisis, efficiency holds one of the key answers in relation to reducing the demand and exploitation of renewables. Power converters, nowadays, provide far more than just an interface between energy sources or demand and the grid. They provide the requested means of control and coordination that smart grids need in order to improve the quality of supply and optimization of available energy resources. Therefore, their efficient operation should not be specified only by reduced energy losses, but increased flexibility and controllability over a wide range of services to the grid and the customer or producer of energy.

In this Special Issue of Energies, authors are invited to contribute their knowledge on novel converter designs that demonstrate the aforementioned properties on known applications or known converter designs that present such properties on new applications or a combination of both. In their works, efficiency can be expressed in terms of conversion losses, but also in terms of controllability and services towards a smarter energy grid. Reviews of the state of the art of high-efficiency converters are also welcome, as long as they clearly demonstrate its applicability in specified research and development areas of smart grids.

Topics of interest for publication include, but are not limited to, efficient converters which:

• interface renewable or conventional micro-sources to the grid;
• are used by critical, non-critical, or elastic demands;
• possess increased controllability;
• provide auxiliary services to the grid (e.g., voltage support);
• provide auxiliary services to the consumers/producers of energy (e.g., power quality);
• promote grid support algorithms during faults and other disturbances.

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. 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.
