Dear Colleagues,

As a crucial sector in the area of sustainable energy application, portable power generation and energy harvesting are still in the initial stage. Along with the great change in the pattern of modern traveling and leisure, there is increasing interest in long-distance outdoor adventures and activities. These scenarios put forward challenging demands for short-time electrical power utilization. Distinct from large station renewable energy generation systems, portable electric generators, together with necessary electrical power devices, converters, and control units, promote the “portable” concept and emphasize the instantaneous energy demand. Potential generators must possess features of high efficiency, high power density, great fault tolerance and reliability, small size, and low cost. Combined with advanced technologies and emerging wireless energy transfer types, the energy generation and harvesting system can be designed and integrated into a variety of portable scenarios or devices, such as pack-based, luggage-based, wearable, onboard, etc. On this basis, this Special Issue focuses on reviews and technical studies on energy generation, harvesting, conversion, and utilization, with regard to these portable application scenarios.

Potential topics include, but are not limited to:

• High-efficiency and high-power-density electric generator topology design;
• Design, analysis, and optimization of rotating/linear permanent magnet generators;
• Fault-tolerant electric generator topology and winding design;
• Monitoring, failure mode analysis, and fault diagnosis of electric generator systems;
• High-efficiency power converter and rectifier systems;
• Integrated design consideration of generator and power converter systems;
• Energy harvesting devices for portable power generation;
• Emerging wireless energy/power transfer technology for portable power generation.

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.
