Title:
METHOD FOR REDUCING STANDBY POWER CONSUMPTION OF POWER SOURCE SYSTEM AND POWER SOURCE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/069142
Kind Code:
A1
Abstract:
A power source system (5) comprises a normal mode detecting and controlling circuit (52), a power-saving mode detecting and controlling circuit (51) and an output circuit (53), wherein the power-saving mode detecting and controlling circuit (51) further includes a non-continuous power-saving mode detecting and controlling circuit unit. A method for reducing standby power consumption of the power source system comprises the following step: bias currents in the non-continuous power-saving mode detecting and controlling circuit unit are increased in a first operating mode and decreased in a second operating mode according to the alternate of operating mode of non-continuous power-saving mode detecting and controlling circuit unit in the power-saving mode. Thus, average standby power consumption of the power source system is reduced and the product is energy saving.
