An inherent fault current blocking modular series multilevel converter using half-bridge sub-modules for grid integration

e-Prime: Advances in Electrical Engineering, Electronics and Energy
This paper proposes an inherent fault current blocking modular series multilevel converter (MSMC) using half-bridge (HB) sub-modules (SMs) for grid integration. The proposed converter uses passive filters to decouple the AC and DC side.

Fragment‐Block: A Novel Approach for Managing Variability in Software Product Lines

Software: Practice and Experience, EarlyView.
ABSTRACT Objective Changes in the functionality of a software product line (SPL) can generate various issues in the SPL source code. Their complexity depends primarily on the amount of changes in the SPL source code and the internal mechanisms for managing variability. Further, modern development frameworks rely on a variety of artefacts besides source
