Abstract

A method and an electronic device for power allocation of multi-parallel power electronic transformers, the method including: determining a quantity of conversion stages of the power electronic transformers; obtaining a load ratio-efficiency relationship between the two ports of each conversion stage in turn, performing a curve fitting to obtain a load ratio-efficiency curve of each conversion stage of the power electronic transformers; calculating a load ratio-loss relationship of each conversion stage, based on the load ratio-efficiency curve of each conversion stage; obtaining a multi-parallel minimum-operation-loss power allocation curve of each conversion stage; performing a piecewise curve fitting of the minimum-operation-loss power allocation curve to obtain a multi-parallel optimum power allocation mathematical model of each stage; and determining an optimum power allocation to each port of the multi-parallel power electronic transformers, based on the multi-parallel optimum power allocation mathematical model of each stage.
