DIFFERENTIAL BACKLIGHT INVERTER

An inverter for a differential backlight is provided to increase a breakdown voltage of a sub-transformer by using a common floating closed-loop circuit for bypassing an excess voltage. An inverter for a differential backlight includes first and second main transformers(100,200) and first and second...

Zusammenfassung:	An inverter for a differential backlight is provided to increase a breakdown voltage of a sub-transformer by using a common floating closed-loop circuit for bypassing an excess voltage. An inverter for a differential backlight includes first and second main transformers(100,200) and first and second sub-transformers(300,400). The first main transformer supplies a first driving voltage for driving plural lamps. The second main transformer supplies a second driving voltage, which has a phase difference of 180 degrees with respect to the first driving voltage. The first sub-transformer includes a first coil group having plural balancing coils and plural lines. The balancing coil is connected between the respective lamps in a first lamp group and the first driving voltage terminal. The line couples the respective lamps in a second lamp group with the second driving voltage terminal. The second sub-transformer includes a second coil group and plural lines.
