摘要

The development of micro grid has become an objective need to crack high permeability distributed energy efficient and secure access to power grid, as the key device of power conversion in micro grid, multi-port converter (MPC) has great application value and broad application pro-spects in the construction of micro grid. This paper first analyzes the development process of power converter topology, on this basis, analyzes and compares the typical topologies of two port converter, three port converter, four port converter and multi port converter for micro grid. Then, it is pointed out that the MPC in power density, conversion efficiency, converter function, etc., has advantages over conventional dual-port converter, which is the future direction of the energy converter. Finally, several key technical problems of MPC to be solved in the engineering application are pointed out from aspects of the topology, power flow control and operation reliability, and the development trend of MPC in micro grid is analyzed from several aspects.
