A current sharing scheme and device for multiple ccf lamp operation

Ring balancer comprising a plurality of balancing transformers 102 is to facilitate the sharing of current in the lamp backlight system. Balancing transformers 102 have respective secondary windings connected together in a given lamp 104. Each of the primary windings are connected in series and are separated from the closed loop. And a common secondary winding is conducting current (Ix), each primary winding is conducting a proportional current (proportional currents) in order to balance the current between the lamp (104). Ring balancer facilitates automatic lamp striking, and the lamp 104 can be advantageously driven by a common voltage source 100.Ring balancer, balancing transformers, fluorescent lamps, current balance, current sharing, backlight system, winding, non-turned
