Title:
METHOD FOR REDUCING POWER CONSUMPTION OF POWER SUPPLY, POWER SUPPLY AUTOMATICALLY REDUCING POWER CONSUMPTION, AND TELEVISION
Document Type and Number:
WIPO Patent Application WO/2018/068452
Kind Code:
A1
Abstract:
A method for reducing the power consumption of a power supply, a power supply automatically reducing power consumption, and a television. The power supply comprises: a voltage sampling circuit (310), an optical coupling feedback circuit (320), a deep standby control circuit (330), a power supply management circuit (340) and an output rectifier filter (350). The output rectifier filter comprises an output capacitor (351). The feedback amount (a second level or a first level) of the optical coupling feedback circuit changes as the capacity of the output capacitor changes, intermittently controlling the power supply management circuit to stop working whist achieving a constant voltage output.
