Energy storage systems with multilevel converters play an important role in modern electric power systems with large-scale renewable energy integration. This paper proposes a reverse-blocking modular multilevel converter for a battery energy storage system (RB-MMC-BESS). Besides integrating distributed low-voltage batteries to medium or high voltage grids, with the inherited advantages of traditional MMCs, the RB-MMC-BESS also provides improved DC fault handling capability. This paper analyzes such a new converter configuration and its operating principles. Control algorithms are developed for AC side power control and the balancing of battery state of charge. The blocking mechanism to manage a DC pole-topole fault analyzed in depth. Comprehensive simulation results validate both the feasibility of the RB-MMC-BESS topology and the effectiveness of the control and fault handling strategies.

“…Because of its characteristic of output voltage regulation in open loop, associated to its feature of soft-switching, the converter became very popular in Smart Transformer (ST) [12] application. Hence, this converter has been used to implement the dc-dc stage of ST's architectures based on modular [13]- [15] and also non-modular [16] concept.…”

Abstract-The series-resonant converter (SRC) has been used in several application and it recently became popular for Smart Transformers (STs). In this application, the efficiency and reliability are of paramount importance. Although many papers have addressed the design challenges to improve the converter efficiency, discussions about the reliability are still missing in literature. In this context, this paper presents a design procedure focusing on the efficiency and reliability improvement of the SRC for ST application. To improve the efficiency, losses modeling in all components is carefully carried out. Additionally, SiliconCarbide (SiC) MOSFETs are used to reduce the conduction and switching losses. The reliability is addressed on the converter design by taking the lifetime of the resonant capacitor and the stress on the main components. Experimental results obtained for the optimized 10 kW series resonant converter has shown an efficiency of 98.61%.
