Special Issue Information

Dear Colleagues,

Over the last decade, lighting systems have experienced great growth towards LED lamps, which requires an equal measure in terms of the development of power electronics technologies.

Power electronics technologies are fundamental for promoting high-quality lighting, always ensuring high efficiency and high reliability under power quality constraints. The adaptation of standards regulation to include new light sources in the market produces a wide variety of electronic topologies and components operating together in the same Low-Voltage (LV) installation compared to other electronic loads as the electric vehicle or a roof-top PV plant. This will lead to new power quality disturbances which might cause equipment to fail, malfunction, or lower in performance depending on the degree of impact. This Special Issue focuses on the power electronic solutions intended to solve power quality disturbances for lighting. The topics of interest include, but are not limited to:

  • Advances in the use of new electrical and electronic components to improve the lifespan of drivers.
  • Power electronic for lighting solutions from the electronic component and topologies point of view.
  • Advances in the AC-DC converter topology that show a high power factor (PF) and efficiency and a low total current harmonic distortion (THD), among others.
  • Advances in the digital control method featuring power factor correction.
  • The flicker measurement and impact in new lighting systems.
  • Low and high frequency (supraharmonic) current emission from lamps: model and simulation.
  • New LED lighting application areas such as agriculture.
  • Power quality impact of the interaction between new lighting systems and other electronic loads.

There are many possible LED lighting applications where separate regulation of the LED current (luminous flux) of individual LED strings would be desirable—specialized variable correlated color temperature lights for ambient lighting, decorative lighting, surgical lights, horticultural lights, etc. Separate regulation of the current or light flux of individual LED strings is associated with a known problem: the necessity of using a controllable LED driver for each string, which increases the total component count, overall system complexity and costs. One of the possible solutions—a current source mode single-inductor multiple-output LED driver—was discussed in previous different papers. However, the practical implementation of this solution was not discussed in detail. This article aims to correct this omission. Full article

Regulating LED current and voltage is critical to maintaining a constant luminous flux in AC- or DC-powered LED lighting circuits. Today, users require constant current drivers that can provide a wide range of output voltages to drive different numbers of series-connected LED arrays. This work proposes an LED driver by combining an isolated SEPIC converter operating in the continuous conduction mode (CCM) and a modified Vienna rectifier. The proposed LED driver offers a single-switch control structure by adding a Vienna rectifier to the integrated SEPIC-FLYBACK converter. This driver structure provides many advantages over traditional bridge rectifier structures. The prototype circuit was tested in an 18 W continuous current mode (CCM) to verify its feasibility. As a result of the values obtained from both simulation and prototype circuit models, it has been shown to provide many of the following advantages: 95% high efficiency, high reliability, 4% low total harmonic distortion, 97% high power factor, and 70 V low switching voltage. This work meets class C 3-2 and IEC 61000 standards. Full article
