Dual-operation-mode DC-DC converter and DC socket for adaptively controlling output voltage

[0037] In one or more embodiments, a DC socket for adaptively controlling output voltage is disclosed, which includes the DC-DC converter with dual operation modes described in Embodiment 1.

[0038] In a specific embodiment, the application scenario of the socket is a household power supply under a medium-low voltage direct current power supply system. For the positive and negative poles, since the grounding method of the DC power supply system is a floating connection, no ground wire is provided.

[0039] refer to figure 1 , The household DC socket with adaptive control output voltage includes: positive socket, negative socket, mechanical spring relay switch, dual operation mode DC-DC converter, positive current conductor and negative current conductor.

[0040] The positive and negative sockets are located at the connection between the socket and the appliance; the mechanical spring relay switch is located on the rear side of the bottom of the positive socket; the dual operat
