Abstract

The invention provides an energy router formed based on interconnection of isolated four-port converters and a converter, and the energy router comprises a plurality of isolated four-port converters, an annular common bus, and an energy storage system. The multiple isolated four-port converters are connected in series end to end through the first ports and the third ports to form an annular structure, the second ports of the multiple isolated four-port converters are all connected with the annular common bus, the energy storage system is connected with the annular common bus, and electric energy exchange can be achieved between the energy storage system and the multiple isolated four-port converters. The DC bus section of the annular common bus between any two adjacent isolated four-port converters and the second ports of any two adjacent isolated four-port converters forms a power distribution subarea, and the DC bus section in the power distribution subarea is used for being connected with a second load. According to the technical scheme, the technical problems that in the prior art, too many converters exist, and the interface converter does not have the electrical isolation function are solved.

Description

technical field [0001] The invention relates to the technical field of converters, in particular to an energy router and a converter based on the interconnection of isolated four-port converters. Background technique [0002] In the prior art, multiple power sources or loads are connected to a common DC bus through their respective power converters in the form of a common DC bus, so as to realize power transmission and regulation. On the one hand, there are a large number of converters in the system. On the other hand, because the interface converters used do not have electrical isolation function, it is difficult to eliminate the negative impact of conductive interference on sensitive loads. Contents of the invention [0003] The invention provides an energy router and a converter based on the interconnection of isolated four-port converters, which can solve the problem of conductive interference on sensitive loads caused by too many converters in the prior art and the in...
