Power supply device and light-emitting device and electronic equipment using such power supply device

Abstract

In a power supply apparatus for supplying a power to a plurality of CCFLs, a plurality of transformers are provided for the respective CCFLs. Respective primary coils of the transformers are connected to each other in series so as to constitute one current path. One ends of respective secondary coils of the transformers are connected to the plurality of loads. An AC power supply unit generates an AC voltage and applies the AC voltage to the other ends of the secondary coils of the plurality of transformers. A capacitor is disposed on the current path formed with the primary coils of the transformers. A first fixed voltage is applied to one end of the current path, and a second fixed potential different from the first fixed voltage is applied to the other end of the current path.
