Abstract
A balancing transforming circuit for cold cathode fluorescent lamps (CCFLs) is provided, which includes a plurality of CCFLs series connected to secondary winding coils of transformers, and a plurality of balancing coils induced with primary winding coils of the transformers. The balancing coils are series connected to form a loop, for balancing the primary winding coils of the transformers, so that the current of each of the CCFLs driven by the transformers are approach to be the same, and all the CCFLs has uniform brightness.
