Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0025] (1) An AC-DC shared electronic load

[0026] An AC-DC shared electronic load according to the present invention, such as figure 1 As shown, the electronic load mainly includes: AC / DC power unit, DC / DC power unit, DC / AC power unit, AC input terminal and DC input terminal. Among them, the input end of the AC / DC power unit is connected to the AC input end; the input end of the DC / DC power unit is connected to the DC input end; the output end of the AC / DC power unit and the DC / DC power unit are connected to the DC bus , the DC bus is used to connect to the grid by connecting to the DC / AC power unit, so as to feed back the electric energy of the AC and DC power supply to the grid. Wherein, switches are respectively connected between the AC / DC power unit and the AC input terminal, and between the DC / DC power unit and the DC input terminal. ...

Abstract

The invention relates to an AC / DC common electronic load, which comprises an AC / DC power unit, a DC / DC power unit, a DC / AC power unit, an AC input end and a DC input end, wherein an input end of the AC / DC power unit is connected with the AC input end; the input end of the DC / DC power unit is connected with the DC input end; the AC / DC power unit and an output end of the DC / DC power unit are connected to a DC bus; the DC bus is used for being connected to a power grid through being connected to the DC / AC power unit; and switches are connected between the AC / DC power unit and the AC input end, and between the DC / DC power unit and the DC input end respectively. The AC / DC common electronic load provided by the invention can change transmission of electric energy in an AC / DC power supply according to the requirements, so that the load is relatively comprehensive in applicability, and has relatively high applicability.

Description

technical field [0001] The invention relates to an AC-DC shared electronic load, which is suitable for the technical field of load access to an AC power grid. Background technique [0002] The load is an important part of the power supply system, and it is an important index to measure the quality of the power supply. Especially in the R&D and test experiments of power supply equipment, it is often necessary to use the load to match the AC and DC power supply equipment, and connect it between the output of the AC and DC power supply and the power grid. The DC power supply is fed back to the grid to simulate the actual working environment load. Most of the traditional loads are pure resistive loads, which easily cause the output energy of the power supply to be converted into heat energy in vain, which increases the R&D and testing costs of power supply equipment; there is also a DC electronic load, but the DC electronic load has low efficiency, harmonic This will lead to un...
