PERFORMANCE COMPARISON OF LLCC RESONANT BASED MULTI OUTPUT CONVERTER AND SINGLE INDUCTOR BOOST BASED MULTI OUTPUT CONVERTER FOR LED DRIVER APPLICATIONS

摘要

The comparison of single-inductor boost based multi output LED driver and chargeexchanging and balancing capacitors based multi output LED driver is proposed in this paper. Theoutput dc current is distributed uniformly to all output channels using equal conduction time of eachoutput in first method. In second method the output current is distributed using primary exchanging(inductor and capacitor (LLC)) and balancing capacitor in secondary side. Both circuit operations arediscussed. The circuit is simulated using matlab. The performance of the circuit is compared and verifiedfrom simulation results.
