The present paper proposes a Fundamental Component Analysis-based Triple Phase Shift (FCA-TPS) modulation strategy for a Dual-Active Bridge (DAB) modular conversion system aimed to green hydrogen production. The proposed FCA-TPS is designed to suppress reverse currents on the DC link output capacitor and to mitigate harmonic content on the high frequency transformer, thus improving system efficiency. A co-simulation study and an experimental investigation on a DAB laboratory prototype validates the effectiveness of the FCA-TPS compared to SPS by achieving an efficiency of 97.4%.

Abstract
The present paper proposes a Fundamental Component Analysis-based Triple Phase Shift (FCA-TPS) modulation strategy for a Dual-Active Bridge (DAB) modular conversion system aimed to green hydrogen production. The proposed FCA-TPS is designed to suppress reverse currents on the DC link output capacitor and to mitigate harmonic content on the high frequency transformer, thus improving system efficiency. A co-simulation study and an experimental investigation on a DAB laboratory prototype validates the effectiveness of the FCA-TPS compared to SPS by achieving an efficiency of 97.4%.
