Proceedings Article
On dynamics and voltage control of the Modular Multilevel Converter
TL;DR: In this article, the authors discuss the impact of modulation on stability issues of the Modular Multilevel Converter (M2C) and suggest a control method that offers stable operation in the whole operation range.
Journal ArticleDOI
Dynamic Analysis of Modular Multilevel Converters
TL;DR: It is shown that the sum capacitor voltage in each arm often can be considered instead of the individual capacitor voltages, thereby significantly reducing the complexity of the system model.
Journal ArticleDOI
Steady-State Analysis of Interaction Between Harmonic Components of Arm and Line Quantities of Modular Multilevel Converters
TL;DR: In this paper, the authors investigated how the arm currents and capacitor voltages interact when the submodules are connected and bypassed in a sinusoidal manner, and derived the analytical expression for the arm current.
Journal ArticleDOI
Open-Loop Control of Modular Multilevel Converters Using Estimation of Stored Energy
Lennart Angquist,Antonios Antonopoulos,Daniel Siemaszko,Kalle Ilves,Michail Vasiladiotis,H-P Nee +5 more
TL;DR: In this paper, a new approach is described based on estimation of the stored energy in the arms by combining the converter electromotive force reference, the measured alternating output current, and the known direct voltage.
Journal ArticleDOI
A New Modulation Method for the Modular Multilevel Converter Allowing Fundamental Switching Frequency
TL;DR: In this article, a modulation method for the modular multilevel converter is proposed based on a fixed pulse pattern where harmonic elimination methods can be applied to achieve stable operation at the fundamental switching frequency without measuring the capacitor voltages or using any other form of feedback control.
