An electrolytic capacitor-less multiple-output LED driver with a universal input voltage

Over the last decades, light-emitting diodes have gained a special position in the lighting market over the conventional lighting sources due to their unique features over them such as their high efficacy, long lifetime, reduced power consumption, and being environmentally friendly. So, in this paper a multiple-output LED driver is proposed, the suggested topology has the advantages of being electrolytic capacitor-less which greatly extends the driver life span, the proposed topology has the ability to control the currents in each output channel independently and operate at a universal range of the supply voltage from 85 Vrms to 265 Vrms.
