Abstract

With the wide application of modular multilevel converters (MMC) in high voltage and high power areas, many open loop methods are proposed for MMC. However, the stability of MMC open loop control system has not been solved so far. Aim at this problem, on the base of Lyapunov theory and persistently and sufficiently exciting (PSE) condition in the adaptive control theory, the uniform asymptotic stability of MMC with capacitor voltage open-loop and without current closed-loop is proved. For the capacitor voltage open-loop balancing control, a soft-rotating phase-shifted carrier (PSC) modulation algorithm is used. Considering the influence of non-ideal factors such as the deviation of capacitance and power tubes' characteristics, the correctness and validity of these results are verified by the simulation.
