Driver system and method for multiple cold-cathode fluorescent lamps and/or external-electrode fluorescent lamps
Abstract:
Driver system and method for multiple cold-cathode fluorescent lamps and/or external-electrode fluorescent lamps. According to an embodiment, the present invention provides a system 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. The system also includes a power converter configured to receive the first AC voltage and convert the first AC voltage to at least a second AC voltage. The system further includes 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 plurality of current balancing devices includes at least a first current balancing device, a second current balancing device, and a third current balancing device. In addition, the system includes a plurality of lamp pairs.
