A CURRENT SHARING SCHEME AND DEVICE FOR MULTIPLE CCF LAMP OPERATION |
摘要 |
A ring balancer comprising a plurality of balancing transformers (102) facilitates current sharing in a multi-lamp backlight system. The balancing transformers (102) have respective primary windings separately coupled in series with designated lamps (104) and have respective secondary windings coupled together in a closed loop. The secondary windings conduct a common current (Ix) and the respective primary windings conduct proportional currents to balance currents among the lamps (104). The ring balancer facilitates automatic lamp striking and the lamps (104) can be advantageously driven by a common voltage source (100). |
