In consequence of the generic irregularity of wave energy, it is difficult to envisage the performance of a grid connected wave energy converter without simulations. This paper details a study on directly driven, linear, permanent magnet generator based, wave energy extraction scheme provided with grid-connected three phase neutral point-clamped three level inverter. The linear permanent magnet generator...
To draw a sinusoidal line current and to achieve high power factor and low voltage stress of power switches, Some single-phase three-level switching mode unidirectional rectifiers with power diodes have been presented. But there is an inherited disadvantage of imbalance of the DC-link voltage, which is difficult to be solved only by control method. A novel three-level rectifier with asymmetrical legs...
