%X Exterior rotor generator improves the efficiencies of wind and wind-energy conversion. Its mathematical model is built in this paper. Based on the characteristics of the double PWM frequency changer, we propose a control strategy for controlling the converter. By means of the AC-DC-AC converter, we convert the generator output with varying-frequency and varying-amplitude into a constant-frequency AC for applications. The optimal usage of wind power is also realized.
