Abstract

A balancing transforming circuit for cold cathode fluorescent lamps (CCFLs) is provided, which includes an inducing coil, secondary winding coils and, a plurality of CCFLs those are series connected to form a CCFL driving loop. A plurality of primary winding coils is induced with secondary winding coils respectively for generating current to drive the CCFLs, so that the CCFLs, which are series connected, has the same current. A balancing loop is provided to be induced with the inducing coil in different CCFL driving loop, so that the current of each of the CCFLs driven by different CCFL driving loop approachs to be the same, and all the CCFLs has uniform brightness.
