Abstract: In this paper, the application of triple-active-bridge (TAB)-isolated bidirectional DC-DC (IBDC) converter for hybrid energy storage system (HESS) in electric vehicle (EV) is considered. The power flow analysis of proposed converter configuration involves coupling of power flow between dc ports. The design procedure involves decoupled power flow management which provides accessibility for independent port power sharing. Simultaneously, it enhances the degree of freedom of control. The objective of this paper is to apply a power decoupling method by which peak power feed by ultra-capacitor of HESS should not affect the continuous steady battery current flow. The proposed method is verified through simulation study as well as experimental study.
