In this paper, a high gain single-stage buck-boost grid-connected system is proposed. The proposed system consists of a high voltage gain - high efficiency - switched inductor buck-boost converter (SIBBC) and a folded cascade H-bridge inverter. The proposed converter switch is derived with a sinusoidal modulation, so that the converter output voltage is a rectified sine wave which requires only a...
Direct-driven wind power generation system has been receiving increasing attention due to its inherent advantage. To realize variable speed operation of the PMSG WECS, a conventional three-phase bridge rectifier with bulky capacitance associated with voltage source current controlled inverter is usually used, which will introduce high intensity low frequency current harmonics into the PMSG and consequently...
