Embodiment 2

[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 ope...

Abstract

The invention discloses a dual-operation mode DC-DC converter and a DC socket for adaptively controlling the output voltage, comprising: a low-voltage DC conversion circuit and a high-voltage DC conversion circuit connected in parallel; an output capacitor C O They are respectively connected in parallel at the output ends of the low-voltage DC conversion circuit and the high-voltage DC conversion circuit; by comparing the required output voltage with the set threshold, the dual-operation mode DC-DC converter can be controlled to work in the low-voltage operation mode or the high-voltage operation mode run mode. The socket of the invention can self-adaptively control the voltage output, avoiding the installation of multi-level voltage output sockets in the household DC power supply system, and reducing the design cost of DC household appliances and the household DC power supply system as a whole.

Description

technical field [0001] The invention relates to the technical fields of direct current electrical appliances and power electronics, in particular to a dual-operation mode DC-DC converter and a direct current socket for self-adaptive control output voltage. Background technique [0002] With the development of distributed energy, the low-voltage DC power supply system will gradually be applied to household power supply. The low-voltage DC power supply system provides DC power, and the corresponding household DC socket is required as an intermediate interface connecting the DC power supply and household appliances. In order to provide high-efficiency power supply in household low-voltage DC power supply systems, there are multiple DC power supply voltage levels, such as 380V and 48V. The inventors found that the existing DC sockets can only output a fixed single voltage, and the multi-voltage level DC power supply system means that DC sockets with different voltage levels need...
