Recent developments in medium-voltage (MV) silicon and silicon carbide (SiC) power
semiconductor devices are challenging state-of-the-art converter and auxiliary power supply …

This article proposes a novel bipolar-type dc system suitable for both distribution and
transmission systems based on modular multilevel series/parallel converters (MMSPCs) …

Submodule (SM) failures are a common fault type in modular multilevel converters (MMCs),
and SM symmetrical bypass guarantees the uninterrupted operation of the system. However …

The technique of single‐source cascaded H‐bridge multilevel inverter (MLI) has been
reported in previous works. In this study, a self‐balanced series/parallel switched‐capacitor …

In order to enable the massive introduction of renewable energies the need for highvoltage
direct current (HVDC) grids is anticipated. Large, globally interconnected HVDC networks …

An improved two-level converter (I2LC) is a practical compromise between the conventional
two-level converter (C2LC) and modular multilevel converter (MMC), recently proposed for …
