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.
