Sažetak
Organic Light-Emitting Diode (OLED) luminaries are planar, diffuse light sources which are powered by DC-DC converters which may use planar inductors to achieve low profile. Challenges in designing the planar inductor stem from the inductor itself, while the other challenges are related to the OLED driver requirements, the electromagnetic compatibility (EMC) and the OLED construction. Large- area luminaries may consist of multiple OLED luminaries, which stresses the importance of the EMC considerations. The optimization of the planar inductor design takes into account both the OLED driver requirements and the EMC issues, and results in the inductor design which introduces minimum power losses in the OLED driver for a given level of radiated emissions. An analytical model of the radiated emissions is developed with respect to the electromagnetic field of an array of planar inductors, i.e. the large-area OLED luminary. The ferrite layers are used to improve the performance of the planar inductor in the OLED luminary, but the geometry of the luminary limits the area of the ferrite layers. The magnetic modelling and measurements of the single-coil and double-coil inductor designs show that the double-coil design represents a more compact and cost- effective design for ferrite layers of limited area. The contributions of the thesis include: electrical and electromagnetic model of planar inductors in low-profile OLED drivers, electromagnetic model of radiated emissions of large-area OLED luminaries and model of ferrite layers applied on planar inductors.
