Abstract：As for the needs of multi-outputwith current balancing in high-power LED applications, the paper proposes a LED driver with multi-output current sharing based on capacitance. Analyzing in detailthe principle of 4-output current balancing, and deducing the equivalent circuit of the resonant network. Keeping the multi-output current constant and balanced based on the CLCL-T resonant network. Finally, a 108W laboratory prototype has been built. The experimental results confirm that the topology presented has good characteristic of current balancing.
