Abstract

The high-power bidirectional DC/DC converter is perceived as one of the key enabling components of DC energy transfer and storage systems, and needs to be designed for high reliability and efficiency. This paper proposes a new high-power input-series-input-parallel output-series (ISIPOS) connected modular DC/DC converter, where the dual-active bridge (DAB) DC/DC converter is employed as the basic module on the primary and secondary sides, with a control strategy that enables power sharing between the modules under any steady-state and transient conditions with mismatched components. In addition, fault tolerant operation is presented. The viability and effectiveness of the proposed control method are demonstrated using MATLAB simulation of power sharing performance and fault tolerant operation.
