In this paper, an integrated LED lamp with an electrolytic capacitor-free driver is considered
to study the coupling effects of both LED and driver's degradations on lamp's lifetime. An …

Gallium nitride (GaN) power semiconductor technology offers a potential for significant
performance increase in power electronic converters. This potential cannot be fully exploited …

Large LED (light-emitting diodes) clusters are currently designed to replace the commonly
lamps used in parks, roadways, tunnels and street lighting. But the success of these designs …

This work presents a simple and effective technique to decrease the driver temperature by
filling the potting materials into space between driver and the interior wall of a LED bulb's …

The low-power consumption, longer lifetime, reliability, and lighting quality are some
features that make the LEDs good candidates to street lighting applications. However, the …

This chapter investigates the reliability of the integrated LED lamps with electrolytic capacitor-
less LED drivers. Firstly, the impact of the interaction between the degradations of the LED …

This work proposes and analyzes modulation strategies for a hybrid three-phase multilevel
inverter, which employs two different topologies in a cascade connection, a three-phase …

High power light emitting diodes (LEDs) have significant contribution in illumination industry
due exceptional advantages in terms of low power consumption, superior reliability …

My very special thanks go to the Prof. Miroslav Husák the head of department who trusted
upon my efforts and encouraged me in taking specific research paths, who managed to …
