Contributions to the modulation and closed-loop control of multilevel dual-active-bridge Dc-Dc converters

, 2017
Galvanically-isolated bidirectional dc-dc converters (IBDCs) have recently received more attention due to its increasing use in systems requiring energy transfer between two dc networks in both directions, requiring galvanic isolation and a high voltage ...
