There has been a growing interest in multi-port converters (MPCs) over the last several years. Applications such as solar and traction are prime candidates for employing MPCs. This paper presents a novel extendable DC-DC MPC which benefits from a uniquely designed hybrid energy storage system (HESS). Compared to the baseline converter, this proposed MPC reduces the number of active switches by 43 percent (from 21 to 12) while reducing the overall number of components by 26 percent. This is accomplished without sacrificing any functionality. The HESS provides the system with a faster response while reducing the main battery's size and enhancing its lifetime. Mathematical analysis and simulation results for this MPC are presented and a prototype of the HESS part is built, and its test results verify mathematical and simulation results.
