Abstract :
In this paper, a novel bidirectional modular multi-level dc-dc converter is proposed. The proposed topology, named the Triangular Modular Multilevel dc-dc Converter (TMMC), can achieve equal power sharing among its modules over a broad range of conversion ratios. The proposed control algorithm provides localized control of modules which enhances the converter´s dynamic performance and design flexibility. A 1.1kW experimental implementation of the converter is shown to achieve an efficiency of 96.3% and 98.0% in step-up and step-down modes, respectively. The TMMC also provides multiple fixed voltage nodes which makes it suitable as a multi-input multi-output converter.
