<P>PROBLEM TO BE SOLVED: To provide a method for driving N pieces of pair lamps by using fewer current balancing circuits and inverter drivers, and a device including the driving circuits of the pair lamps and basic circuit blocks used for them. <P>SOLUTION: Transformers connected to one or a plurality of the inverter drivers are used to drive the plurality of lamps. Each transformer has first and second coils magnetically coupled with each other, each coil having an input terminal and an output terminal, and the transformer is connected to the input terminal of the first and second coils, and receives input current. The output terminals of the first and second coils provide output currents of two different balancing current paths, a capacitor is provided furthermore between the input terminal and the output terminal of the respective first and second coils, and a basic current block of the driving circuit of the transformer is formed, and the transformer has an input block to receive the input current and two output blocks for providing the output currents of two different balancing current paths. <P>COPYRIGHT: (C)2007,JPO&INPIT |
