A Triple Active Bridge-Based Topology for Power Management in Green Hydrogen Production

This paper proposes a DC/DC isolated conversion system based on the Triple-Active Bridge (TAB) topology for green hydrogen production. Specifically, the configuration involving a Photovoltaic (PV) power plant and an Energy Storage System (ESS) is investigated. The TAB’s quasi-inherent decoupling feature and the use of Virtual Direct Power Control (VDPC) enable effective and independent management of power flows from the PV and ESS, even in the event that one of the sources fail and the ESS is charging due to PV overproduction. A simulation study on PLECS demonstrates the efficacy of the proposed configuration and shows that the system can manage the power flow of the TAB ports independently.
