The rapid conversion of automotive accessory loads to the electrical domain demands a power converter to interface between the on-board source and storage units with the accessories. This study proposes a simplified structure of dual input dual output (DIDO) with single-stage power conversion for hybrid electric vehicle accessory applications. The topology is synthesised using pulsating source cells. The generic switch model-based DIDO is realised with power switches based on switch realisation technique. Steady-state and equivalent circuit models describing the converter structure are presented. Numerical simulations were performed with the state-space averaged mathematical model. A one-step-ahead controller is used for inductor current control in conjunction with a mode selection logic to utilise its operating modes based on the availability of the sources and its protection. The performance of the proposed converter and its associated control scheme under steady-state, transient conditions are corroborated by simulation and experimental results.
