DOI: 10.1109/tpel.2021.3077562
Abstract: A three-phase three-level converter with an LCL filter has been used in the industry because of its low switching harmonics. However, it inevitably suffers from dc neutral-point imbalance, which may unnecessarily stress semiconductors and deteriorate… read more here.

DOI: 10.1109/tpwrd.2019.2956723
Abstract: This article proposes a hybrid three-level converter (H3LC) with AC-side cascaded full-bridge submodules (FBSM) for high voltage direct current (HVDC) transmission. The three-level converter operates at fundamental frequency switching to modulate square-wave output voltages. The… read more here.
