Abstract	The increasing adoption of Electric Vehicles (EVs) demands efficient and scalable fast charging infrastructure. Conventional fast charging systems rely on Full Power Processing (FPP), where the entire power is processed through converters, resulting in high losses, increased cost, and poor efficiency at partial loads. This paper proposes a Partial Power Processing (PPP)-based multiport DC-DC converter architecture for EV fast charging applications. The proposed system utilizes a bidirectional buck converter for bulk power transfer and multiple Dual Active Bridge (DAB) converters for differential power processing. The system is modelled and simulated in MATLAB/Simulink to evaluate performance in terms of efficiency, power distribution, and voltage regulation. Results demonstrate that the proposed PPP architecture significantly reduces converter power rating and improves overall efficiency compared to conventional FPP systems.
