摘要
This paper provides a detailed analysis of a novel method for reducing DC bus capacitance in the three-phase power electronic transformer (PET). In order to further improve power density, a double frequency power transmission (DFPT) control method is proposed. The voltage fluctuation can be partly reduced by DFPT method but with a certain price. In this paper, on the basis of previous studies, the effects of this method on DAB efficiency, device capacity and stability are studied in detail. Simulation and practical experiments are carried out to verify the analysis results.
