Abstract
Embodiments of the present invention disclose a circuit structure and a method for reducing power consumption of a device including an active module and a passive module. The circuit structure comprises: an active module () comprising a main output voltage () for powering a load () via a first current control device () which is configured to control a current passing through the load (), and an passive module () comprising a main output voltage () for when the active module () fails, powering the load () via a second current control device () which is configured to control a current passing through the load (). The passive module () further comprises an auxiliary output voltage () for when the passive module () is in a backup state, powering the second current control device () so as to enable the second current control device () to be in a switching-on state. Further, the auxiliary output voltage () of the passive module () is configured to be smaller than the main output voltage () of the passive module ().
