A nearest level PWM method for the MMC in DC distribution grids [PDF]

, 2018
For modular multilevel converters (MMCs) applied to medium-voltage DC distribution grids, using the traditional Nearest Level Modulation (NLM) as in HVDC systems can lead to severe current distortion due to significantly reduced module number. This paper

A Soft-Switching Control for Cascaded Buck-Boost Converters Without Zero-Crossing Detection

IEEE Access, 2019
This paper proposes a novel soft-switching control without zero-crossing detection for the cascaded buck-boost converters (CBBCs). The proposed soft-switching control consists of two parts: soft-switching modulation and closed-loop control.
