Patent ID: 7164240

Claim:
A device comprising: an External Electrode Fluorescent Lamp (EEFL) having a first end and a second end; a first bridge cap tunable to remove capacitive current from a signal; a first transformer having a secondary winding, wherein the secondary winding of the first transformer is operationally connected to the first end of the EEFL and to the first bridge cap; a second bridge cap tunable to remove capacitive current from a signal; a second transformer having a secondary winding, wherein the secondary winding of the second transformer is operationally connected to the second end of the EEFL and the to the second bridge cap; a sense resistor for facilitating feedback of a first signal from the first bridge cap and a second signal from the second bridge cap, wherein the first signal includes a load current associated with the EEFL and the second signal includes a load current associated with the EEFL, wherein, in operation, the first signal has capacitive current associated with the first end of the EEFL removed by the first bridge cap and the second signal has capacitive current associated with the second end of the EEFL removed by the second bridge cap.
