Abstract
A balancing transforming circuit for cold cathode fluorescent lamps (CCFLs) is provided, which includes a plural pairs of CCFLs driven by a plurality of transformers. A secondary winding balancing loop is adopted for balancing secondary winding coils of the transformers, such that the current of the CCFLs is balanced and each of the CCFLs has uniform brightness.
