“…Ref. [15] presents a series-resonant converter (SRC), which can be used as a power control stage able to reduce the low-frequency ripple of the LED current. Additionally, a good performance of the system is gained due to the low switching losses of the SRC and by using film capacitors instead of electrolytic capacitance at the output of power factor correction (PFC) stage.…”

The study analyses the performance of different LED circuit configurations feed from a low power resonant driver under pulse quasi-triangular currents. The considered LED driver topology is based on a bridgeless single-stage AC-AC converter with bidirectional switches and a parallel LC resonant tank. The converter performances are simultaneously analyzed in correlation with the most important features, such as the electric efficiency, luminous efficacy, power factor correction capabilities, and flickering implications.
