Compared to the conventional buck topology, the HS-L buck has lower losses attributed to lower conduction losses in the inductor and diode, and a wider discontinuous conduction mode range. Experimental results verify higher efficiency using the HS-L buck compared to the conventional buck topology, achieving efficiency above 92% and power factor above 0.9 over the universal input range. © 2004-2012 IEEE.clamped current mode control; hybrid switched-inductor buck; LED driver; Power factor correction (PFC)[SDGs]SDG7DC-DC converters; Efficiency; Electric power factor correction; Light emitting diodes; Topology; Coupled inductor; Current Mode Control; Discontinuous conduction mode; Higher efficiency; LED drivers; Lower conduction loss; Power factor corrections; Switched inductors; Electric inductorsjournal article10.1109/tcsii.2017.27875542-s2.0-85040079272
