Special Issue Information

Dear Colleagues,

Due to their excellent physical properties, gallium nitride (GaN) electric devices that can operate at a high switching frequency can drastically improve the energy conversion efficiency, reduce the volume of energy storage components, and scale down the system form factor. GaN has become one of the most promising materials in the area of high-power and high-temperature power electronics, and it is considered the material that will revolutionize the future of power electronics.

Impressive progress has already been achieved in lateral and vertical GaN device technologies, from advanced epitaxial growth approaches to novel or cost-effective device structures as well as innovative processing methods, more in-depth device physical analysis, and monolithic integration of GaN-based power electronic devices.

The main aim of this Special Issue is to bring the latest and most important innovations in GaN-based power electronic devices and their applications, address recent breakthroughs in GaN power electronics, and provide an up-to-date picture of current challenges and future development.

The topics covered in this Special Issue include but are not limited to simulation and modelling, device and integration design, epitaxy, processing technology, reliability and failure analysis, advanced characterizations, and applications.

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. Electronics 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 2400 CHF (Swiss Francs).

In this article, a fully monolithically integrated GaN power stage with a half-bridge, driver, level shifter, dead time and voltage mode control for 48 V DC–DC converters is proposed and analyzed. The design of the GaN IC is presented in detail, and measurements of the single function blocks and the DC–DC converter up to 48 V are shown. Finally, considerations are given on a life cycle assessment with regard to the GaN power integration. This GaN power IC or stage demonstrates a higher level of integration, resulting in a reduced bill of materials and therefore lower climate impact. Full article
