Comparison of the Modular Multilevel DC Converter and the Dual-Active Bridge Converter for Power Conversion in HVDC and MVDC Grids
TL;DR: In this article, the authors compared the performance of the modular multilevel dc converter (M2DC) and the three-phase dual-active bridge converter (DAB) in terms of efficiency, amount of semiconductor devices, and expense on capacitive storage and magnetic components.
Journal ArticleDOI
Dynamic and Balanced Control of Three-Phase High-Power Dual-Active Bridge DC–DC Converters in DC-Grid Applications
TL;DR: In this article, the dynamic behavior of a three-phase dual-active bridge (DAB) is analyzed and a dynamic control strategy is developed, and a compensation technique is implemented to compensate unbalanced transformer phase currents.
Proceedings Article
Control of the Modular Multi-Level Converter for minimized cell capacitance
TL;DR: In this article, a method to minimize the required cell capacitance for a given point of operation (modulation index, displacement factor) by means of injecting harmonics into the circulating current is presented.
Journal ArticleDOI
Improved Instantaneous Current Control for High-Power Three-Phase Dual-Active Bridge DC–DC Converters
TL;DR: In this article, the authors proposed two control schemes that reach steady state in one-third and half a switching period, respectively, for the three-phase dual-active bridge.
Proceedings ArticleDOI
Instantaneous current control for the three-phase dual-active bridge DC-DC converter
TL;DR: In this article, the dynamic behavior of three-phase dual-active bridge (DAB) is analyzed and a dynamic control strategy is developed, and a compensation technique is implemented to compensate unbalanced transformer phase currents.
