Title:
POWER EXTENSION SOCKET
Document Type and Number:
WIPO Patent Application WO/2017/004877
Kind Code:
A1
Abstract:
A power extension socket (100) comprises: a power input interface (110), used to receive an AC; an AC-DC conversion circuit (130), connected to the power input interface (110), and used to convert the AC into a DC having a pre-set voltage and output the DC; a DC output interface (120), connected to an external device, and used to output the DC to the external device; a voltage detection circuit (140), connected to the DC output interface (120), and used to detect a power supply voltage demanded by the external device when the external device is connected to the DC output interface (120); and a DC voltage stabilizing circuit (150), connected to the voltage detection circuit (140), the AC-DC conversion circuit (130), and the DC output interface (120) separately, and used to perform voltage conversion on the DC according to the power supply voltage and then output the DC to the DC output interface (120).
