Abstract During normal operation of a conventional Modular Multilevel Converter (MMC), half of its capacitors remain bypassed at any time instant, increasing the total required capacitance for converter operation, and in turn leading to a larger size

The modular multilevel converter (MMC) is the most promising topology for the medium/high-voltage applications. Recently, a novel type of switched-capacitor MMC (SCMMC) has been proposed, which has inherent capacitor voltage balancing function and hi

Stability Control and Reliable Performance of Wind Turbines
Due to wind turbine is in class of complex nonlinear system so the precise model of this plant is not accessible, therefore it can be categorized as an uncertain model. So, controlling of this system is a demanding topic. Many of schemes which presen

In this paper a controller is designed for voltage source converters (VSC) using Nyquist array. Real systems existing in industry are nonlinear systems with multiple inputs and multiple outputs (MIMO). Such systems are always affected by different un
