DRIVER SYSTEM AND METHOD WITH CYCLIC CONFIGURATION FOR MULTIPLE COLD-CATHODE FLUORESCENT LAMPS AND/OR EXTERNAL-ELECTRODE FLUORESCENT LAMPS

摘要

System and method for driving a plurality of cold-cathode fluorescent lamps. The system includes a subsystem configured to receive at least a DC voltage and generate a first AC voltage in response to at least the DC voltage, a power converter configured to receive the first AC voltage and convert the first AC voltage to at least a second AC voltage, and a plurality of current balancing devices. Each of the plurality of current balancing devices is configured to receive two currents and balance the two currents. The power converter and the plurality of current balancing devices are capable of being directly or indirectly coupled to a plurality of cold-cathode fluorescent lamps.
