Abstract
This paper presents a new current balancing operation for LED using double-step-down dc-dc converter. The two output currents of the proposed converter can be balanced by charge balance condition although the two output resistances are different. In addition, voltage stresses of the switches of the proposed converter are lower than those of interleaved buck converter. To verify the operation of the proposed converter, simulation program is used.
