“…This topology was later applied to a PMSG-based wind energy system also placing a three-phase LC filter and a three-phase boost coil between the generator and the rectifier [18]. A similar configuration, only using the three-phase capacitor bank and three-phase boost inductor was used in [19]. The elimination of the DC capacitor after the rectifier has also been proposed to reduce the generator torque ripple [20].…”

This paper analyzes a cost-effective modification of the power topology commonly found in small wind turbine systems based on a passive rectifier and a boost converter. The boost converter inductor and the input filter capacitor often placed at the rectifier output can be replaced by the generator phase inductance. Different controller structures have been proposed for this low-cost inverter, but they have been focused in the converter itself rather than in the overall turbine control. Moreover, only steady-state behavior has been demonstrated. This paper proposes a control structure only requiring retuning of the boost current controller found in systems equipped with boost inductance; other control loops remaining unchanged. The inductorless converter dynamic performance is studied and compared with the conventional topology in terms on current and torque control capability. The system efficiency, including the losses distribution in the generator, is analyzed. Simulation and experimental results are presented to demonstrate the technical viability of this proposal.

“…The most widely used converter topology on the generator side for low-power grid-tied systems consists of a diode rectifier and a boost converter [5]- [11], [25]. Alternatively a boost rectifier has also been proposed [26]. An active rectifier with only three active switches was proposed in [19].…”

Abstract-This paper proposes a new soft-stalling control strategy for grid-connected small wind turbines operating in the high and very high wind speed conditions. The proposed method is driven by the the rated current/torque limits of the electrical machine and/or the power converter, instead of the rated power of the connected load, which is the limiting factor in other methods. The developed strategy additionally deals with the problem of system startup preventing the generator from accelerating to an uncontrollable operating point under a high wind speed situation. This is accomplished using only voltage and current sensors, not being required direct measurements of the wind speed nor the generator speed. The proposed method is applied to a small wind turbine system consisting of a permanent magnet synchronous generator and a simple power converter topology. Simulation and experimental results are included to demonstrate the performance of the proposed method. The paper also shows the limitations of using the stator back-emf to estimate the rotor speed in permanent magnet synchronous generators connected to a rectifier, due to significant d-axis current at high load.
