Characteristics Analysis of Capacitor Voltage Ripples and Dimensioning of Full-Bridge MMC With Zero Sequence Voltage Injection

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019
Compared to the conventional half-bridge submodule-based modular multilevel converter (MMC), the full-bridge submodule (FBSM) capacitance of FB-MMC can be reduced significantly with consideration of negative voltage state of the FBSM, which has benefits to cost and size reduction.

Air-Gap Flux Position Estimation of Inaccessible Neutral Induction Machines by Zero-Sequence Voltage

Electric Power Components and Systems, 2002
This paper describes a new and straightforward approach to estimate the air-gap flux position in induction machines. The proposed scheme is based on the injection of a high-frequency oscillating stator voltage instead of a three-phase high-frequency voltage, thus allowing a reduction in audible noises and torque ripple. The main feature of the proposed

Minimizing the battery losses in MMC via Zero-Sequence Voltage injection: an open challenge

2024 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)
This work focuses on battery-powered Modular Multilevel Converters (MMC) and explores several methods aimed at improving overall efficiency by reducing the energy losses of electrochemical sources. MMCs represent a valid alternative to more traditional structures such as Voltage Source Inverters (VSI) because they possess several advantages.
