abstract

  • This paper describes a modular architecture based on the dual-active bridge (DAB) converter in input-series-output-parallel (ISOP) connection. This work is focused on the input voltage sharing to ensure a proper operation of each module by means of an active control of input and output voltages. A small-signal model of the modular architecture is proposed and a decoupled control loops' scheme is used to implement the control strategy. An experimental setup has been built in order to validate the model of the DAB converter in ISOP connection and the proposed control strategy, taking different operating conditions and constructive parameter values into account.
