| Abstract |
This paper examines a modulation strategy called V-theta control, designed for six-switch controlled rectifiers in small-scale wind turbines. In this strategy, surface permanent magnet (SPM) generator torque is commanded by controlling the magnitude of the phase voltage and its phase shift with respect to the current. Simulated results obtained using simplified and PWM inclusive models were used to validate the analytical findings presented. Lastly, experiments comparing V-theta, phase advance and conventional switched-mode rectifier (SMR) modulated AC/DC converters across a range of generator speeds. V-theta; control was found to produce up to 22\% more power when compared to phase advance modulation, the control technique with the closest performance. |
