A multiple-string hybrid LED driver with 97% power efficiency and 0.996 power factor

This paper presents a multiple-string hybrid LED driver powered by 100-120VAC input for general lighting applications. The proposed hybrid LED driver adaptively switches between Linear Mode and Switching Mode according to the input voltage to enhance the power efficiency. This work achieves 97% power efficiency and 0.996 power factor at 120VAC 60Hz input.
