Refined Modeling and Bi-directional Power Flow Control of Reversible Solid Oxide Cell

Modeling and Control Design for a Bidirectional DC-DC Converter System for Cyclic Operation of a Reversible Solid Oxide Electrolysis Cell Stack

“…Different bidirectional power converter topologies for interfacing with an RSOC stack have been investigated. These include the non-isolated bidirectional DC-DC converter topologies: Buck-Boost Converter (BBC) [7] and interleaved buck-boost converter [8] and the isolated bidirectional DC-DC converter topologies: Isolated full bridge boost converter [9]- [11], dual-active bridge [11]- [13], and cascaded converter structures [13]- [15]. The cyclic operation of a RSOEC stack imposes additional challenging requirements for the bidirectional DC-DC converter system, such as fast tracking performance during reversible operation mode and properly damped oscillations.…”
