  • Patent number: 7190128
    Abstract: A multi-lamp driving system for driving lamp units includes a multi-phase alternating current (AC) power generating unit for generating a plurality of out-of-phase AC current signals, and a balancing unit for balancing current flowing through each lamp unit. The balancing unit includes a plurality of loads, and a multi-phase transformer that has a plurality of coils. Each lamp unit is adapted to be connected to at least one of a respective load and a respective coil, and forms a series connection with the respective load and the respective coil. The series connection of each lamp unit with the respective load and the respective coil is coupled across the AC power generating unit.
