Special Issue Information

Dear Colleagues,

Machine drives, including the machine, the associated power electronic converters and their control, play a very important role in converting renewable energy into usable electrical energy. New technological advances in such systems are helping to convert renewable energy more efficiently and reliably. Various new families, topologies and technologies have recently been introduced, and are constantly being improved. In fact, the trend of creating flexible design processes that simultaneously allow for component-level, sub-system-level and system-level design is becoming ever more important, as developers and end-users look to achieve the optimal performance possible.

Application-oriented design processes are also changing. While certain technologies are inherently more suited to a particular application, there is currently also a trend to investigate the adaption of technologies across application areas.

This Special Issue is thus intended for researchers and practitioners to share their latest research findings and limitations that can be addressed in future research in machines and power converters for renewable power generation. Research including experimental validation or field testing is highly encouraged for submission. Position papers and state-of-the-art reviews are also welcomed. 

This Special Issue invites papers that cover topics including but not limited to the following:

  • Advances in machine design (power density, efficiency, robustness, etc.);
  • Advances in drive and power electronic converter topologies (new, high voltage, efficiency, resilient, fault tolerant, power take-off, etc.);
  • Advances in system and component reliability-oriented design aspects (general life consumption and degradation of machines and power converters, general lifetime predictions of machines and converters, conditioning monitoring, prediction and assessment of failures, insulation degradation, etc.);
  • Advances in design strategies for applying and implementing technologies across disciplines and/or renewable areas;
  • Advances in control strategies (high performance, estimation of non-measurable parameters, mitigation of loads, grid integration and grid support, etc.).

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.

This article investigates the comparison between two configurations of 20 MW offshore synchronous wind generators using ferrite and rare-earth permanent magnets. The optimization-based comparison concerns the torque ripple and active mass, which are two crucial criteria for offshore wind generators. Both generators adopt surface-mounted permanent magnet type with direct-drive technology to avoid problems associated with the gearboxes. The result shows that at the full-load condition, the ferrite permanent magnet generator can reduce the torque ripple to as much as 0.12%, while the rare-earth counterpart can be about 2.5 times lighter than the former one.
