Modulated Parameter-Less Predictive Voltage Control for Dual-Active-Bridge Converters

Conventional model-based predictive voltage control in dual-active-bridge (DAB) converters suffers from voltage regulation limitations because the limited phase-shift angle candidate set impacts dynamic response and the parametric sensitivity impacts robustness. To address above limitations, this paper proposes a modulated parameter-less predictive voltage control (MPL-PVC), where a parameter-less modeling architecture replaces conventional mathematical models, eliminating dependency on precise circuit parameters through real-time parameter-less model updating, and a modulated optimal phase-shift angle calculation replaces conventional phase-shift angle candidate set, enhancing voltage regulation capacity while decoupling control performance from parametric variations. Experimental validation on a DAB prototype confirms the effectiveness of proposed MPL-PVC in enhancing dynamic performance and eliminating parametric effect.
