Abstract

The invention relates to the technical field of power equipment, in particular to a multi-port power electronic transformer topological structure and an AC / DC microgrid system thereof, and the multi-port power electronic transformer topological structure comprises at least two alternating current input ends; at least two groups of voltage conversion units, correspondingly connected with the alternating-current input ports, each group of voltage conversion units comprising a preset number of voltage conversion subunits, and each voltage conversion subunit outputting direct-current voltages of at least two voltage classes; the direct-current voltage output ends of the same voltage class in each group of voltage conversion units being connected in parallel to form a first direct-current voltage output end of each group of voltage conversion units; at least two groups of direct-current voltage output ends, comprising second direct-current voltage output ends formed by connecting the firstdirect-current voltage output ends of the at least two groups of voltage conversion units in parallel; and at least one group of AC voltage output ends connected with the second DC voltage output end.And high-voltage, low-voltage, alternating-current and direct-current ports are provided, so that flexible networking can be realized.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a topology structure of a multi-port power electronic transformer and an AC / DC microgrid system. Background technique [0002] The basic idea of ​​the power electronic transformer (Electronic Power Transformer, referred to as EPT) is to replace the power frequency transformer with a high-frequency transformer, and at the same time introduce power electronic conversion technology on the source side and the secondary side of the high-frequency transformer, and realize the transformation of the transformer through appropriate control. Flexible adjustment of voltage, current and power on both sides. At present, power electronic transformers have been widely used in distribution network. [0003] Among them, the existing power electronic transformers are mostly high and low voltage ports. However, with a high proportion of new energy access and a large number of applications...
