Özet

This paper presents the comparison of LED driver topologies that include buck-boost and SEPIC converters. Both topologies are connected to grid over single phase diode rectifier and designed for 8W power. Furthermore, buck-boost and SEPIC converters operate with 63 kHz switching frequency and inductors of SEPIC are wounded as coupled. By means of the implementations, power factor (PF) and total harmonic distortion (THD) of current and voltage, power LED voltage and current are shown for both topologies. Comparison is also made between IEC61000-3-2 standard, buck-boost and SEPIC converters. Besides, electrical circuit model of power LED is derived by using its current-voltage characteristic.
