Abstract
A system for driving a CCFL lamp module having a first CCFL and a second CCFL is provided. The system includes a first direct current (DC) power and a second direct current power; a first direct current/ alternating current (AC) converter and a second direct current/ alternating current converter for respectively converting input direct current voltages to alternating current voltages; a first transformer and a second transformer for transforming the alternating current voltages; a first common-mode choke and a second common-mode choke for balancing the current flowing through the CCFLs in the CCFL lamp module; a first feedback circuit and a second feedback circuit for feeding back the current flowing through the CCFL lamp module to the direct current/ alternating current converter.
