A comparative study the percent flicker and photometric measurement in three-phase and single-phase drivers

Abstract

This paper presents the evaluation of a single-phase topology and a three-phase topology. Photometric and flicker characteristics were compared. To validate the results, a single-phase charge-pump driver for power LEDs driving a 22 W luminaire, and a three-phase driver with a switched capacitor was used for power LEDs driving a 216 W luminaire. The obtained results were compared with the actual norms. The three-phase driver is operating within the recommended operating region in Std. 1789-2015, while the single-phase driver is operating outside the recommended region.
