Özet

This paper presents a comparison of LED driver topologies that include linear and buck-boost converters. Both topologies are connected to grid over a single-phase diode rectifier and designed for 8 W power. Further, buck-boost converters work on a discontinuous conduction mode (DCM) with 63 kHz switching frequency. Finally, power factor and total harmonic distortion (THD) of current and voltage, power LED voltage and current are shown for both topologies over implementations, and a comparison is made. Furthermore, voltage-current characteristic, current and voltage- illuminance characteristics are derived.
