  • A novel resonant single-switch multi-string boost LED driver converter was proposed, the operation principle and characteristics of which were analyzed. It can achieve current balancing among 2n LED strings by using only one active switch, one resonant inductor and 2n-1 resonant capacitors. Thus it boasts the benefits of simple circuit structure and control, small volume, high efficiency and low cost. By controlling only one output current, the other output currents of this LED driver can be controlled utilizing the charge balance principle of resonant capacitors. If one output branch of the LED driver is short-circuit in the steady state, it will not affect current sharing among the other output currents. Therefore, it has a characteristic of natural short-circuit protection. Finally, the theoretical analysis is verified by a 48 W four-string prototype.
