N2 - This paper proposes a new three-port partial power DC-DC converter (PPC), which allows the combined ACDC on-board fast charging from grid and battery energy storage system, simultaneously. The concept of partial power conversion reduces the power processed by the grid port and also supports the higher charging rate, as the converter power density and efficiency are considerably improved over the conventional full power processing converter (F - PPC). The proposed topology is derived using a triple active half bridge converter (TAHB), which integrates the functions of multiple AC-DC and DC-DC converters in conventional fast charging station into one threeport converter. The proposed topology has minimal number of components and ensures that most of the charging power is taken through BESS. The PPC design further, helps in achieving smaller rating devices in the converter due to reduced power processing for the conversion. The design of the converter is discussed in detail and dynamic performance is verified using MATLAB/Simulink based assessment. For a 17kW rating, the efficiency of the proposed TAHB converter for combined AC-DC charging is compared with the conventional FPP converter-based charger.
