Cyber-Attacks in Modular Multilevel Converters
IEEE Transactions on Power Electronics, 2022 Distributed control of modular multilevel converter (MMC) submodules offers several potential benefits such as flexibility and modularity. In this approach, low-level control tasks, such as capacitor voltage balancing, can be distributed amongst controllers placed in the SMs.

Advanced Functional Materials, EarlyView.A fully programmable, dual‐inductive switchable halide perovskite memristor is demonstrated through precise BDAI2‐mediated interface engineering. This ion‐modulating layer suppresses stochastic filamentary growth, enabling stable, non‐filamentary switching via dynamic barrier modulation.
