Maximum power point tracking for direct driving nine-phase FSPM wind generator

This paper proposed a maximum power point tracking (MPPT) control algorithm based on power feedback for the FSPM generator. To eliminate excessive harmonic currents which caused by traditional control algorithm, the SVPWM based on vector space decomposition is adopted. With the optimal reference power curve, the MPPT is realized by pulse width modulation (PWM) inverter. Both simulation and experiment results proved the effectiveness of the proposed control strategy.
