Special Issue Description

When current flows through a light-emitting diode (LED), it emits light. Electrons in the semiconductor recombine, releasing energy in the form of photons (Energy packets). The energy required for electrons to cross the semiconductor’s band gap determines the color of the light (corresponding to the energy of photons). Multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device are used to generate white light. LEDs are used as status indicators and displays on a variety of equipment and installations due to their low energy consumption, low maintenance, and small size. Large-area LED displays are used in stadiums, as dynamic decorative displays, and as freeway message signs. LED devices can outlast the power electronic components needed to drive them in terms of longevity. Failures of aluminum electrolytic capacitors (AECs), primarily as a result of aging and temperature impacts, are the leading contributors to the breakdown of power electronic equipment. This emphasizes how crucial it is to provide reliable power converter architectures and control strategies that permit the assessment of electrolytic capacitor status while retaining the functionality of converter controllers even in the case of capacitor failure. Due to the unique architecture and low ratings of the most modern LED lighting systems, this work presents a novel condition-monitoring system for the identification of capacitor problems on a fault-tolerant LED driver.

Manuscripts should be submitted online via the manuscript Engine. Once you register on APID, 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 email address:[email protected] 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 Double-blind peer-review process. A guide for authors and other relevant information for the submission of manuscripts is available on the Instructions for Authors page.
