An LMI-Based Linear Quadratic Regulator (LQR) Control for Modular Multilevel Converters (MMCs) Considering Parameters Uncertainty

IEEE Access
This paper presents the robust linear quadratic regulator (LQR) control for the uncertain modular multilevel converters (MMCs). The classical LQR control prioritizes optimizing the performance index but lacks the ability to address converter ...

A Low Inrush Current Pre-Charging Strategy of M3C with Improved Nearest Level Modulation

Energies
The modular multilevel matrix converter (M3C) can perform AC/AC conversion directly. However, M3C operation often requires a pre-charging process, which can be challenging due to the need for fast pre-charging with low inrush current.
