WIPO Patent Application WO/2008/046253
Kind Code:
A1
Abstract:
A second-stage transformer system, wherein a first-stage transformer can be plugged
in plug jacks, such as receptacles. Ac power supply is reduced to low voltage by
the first-stage transformer considerably. Further, when voltage of electronic equipments
is the same as the voltage of the first-stage transformer, the said electronic
equipments can be used. It is not necessary to configure an additional transformer.
When the voltage of the first electronic equipment is lower than second voltage
of the first-stage transformer, another second-stage transformer can be used.
The step-down ratio of the second-stage transformer is reduced and the volume
of it becomes small.
