This paper presents the two configurations of partial power processing converter for onboard electric vehicles (EVs) charging using the traditional full power processing dual active bridge DC-DC converter. The two configurations are Input Parallel and Output Series (IPOS) Series Output Parallel (ISOP) partial power converters for high- and low-voltage battery charging applications. IPOS and ISOP can bidirectional power transfer from source to battery and vice-versa through the direct and partial paths. The partial path only comprises passive and magnetic components, whereas no components are on the direct path. To validate the performance of the proposed configurations of partial power processing, converters have been simulated and tested using MATLAB / Simulink toolbox, and their results are compared with the full-power processing dual active bridge converter under the various loaded conditions. The results show that the IPOS and ISOP configurations provide an efficiency of about 94% under full load conditions, i.e., during battery charging and observed to be 4–6% higher than the full power converter configuration. Also, IPOS and ISOP schemes handle less than 50% of output power via the partial paths. Therefore, power ratings and sizes of the semiconductor and passive devices can be significantly reduced compared to the full power converter. Hence, it is observed that these two configurations are best suited for onboard EV chargers.
