Generic Method for Instantaneous Flux and Current Control of the Single-Phase and Multi-Phase Dual-Active Bridge

The variety of optimized modulation schemes for the Dual-Active Bridge (DAB) is a significant challenge in the design of fast transient control methods which still exploit all scheme-specific advantages, especially when inter-scheme transitions are involved. This paper presents a generic Instantaneous Flux and Current Control method for a complete class of frequently used modulation schemes. It preserves all characteristics of the original schemes and enables therefore easy use of their benefits.
