Featuring high efficiency, low harmonic distortion, high modularity and scalability, the modular multilevel converter (MMC) is particularly suitable for high voltage direct current transmission applications. As an advanced control strategy, model predictive control (MPC) has the advantage of direct modeling and fast dynamic response. It can simultaneously control multiple variables through an appropriate...
Due to the demand for increasing the reliability and efficiency of Shunt Active Power Filter (SAPF), this paper proposes a novel fault-tolerant control scheme for SAPF. When phase failure occurs, the inverter topology can be reconfigured from three-phase six-switch structure into three-phase four-switch which is achieved by connecting the endpoint of fault phase to the midpoint of DC-bus. On this...
This paper focuses on a battery charging technology utilized in the small wind power generation system, in which the cost should be especially emphasized. An algorithm to make the input voltage track its reference rapidly is proposed in this paper. Meanwhile, a new control strategy is adopted to restrain the charging current by means of dynamically confining the duty-cycle of the buck converter. At...
