Optimum extraction of energy from a wind turbine requires that turbine speed vary with wind speed. Existing solutions to produce constant-frequency electrical output under windspeed variations are undesirable due to complexity, cost, inefficiency or reliability issues. We propose a novel variation of a doubly-fed induction generator which aims to improve power density and simplify construction. Our design is a doubly-fed, dual-rotor, axial-flux, permanent-magnet machine. Progress in the construction of a prototype is described. Analysis of the steady state and dynamic behavior of the machine is detailed, and a control algorithm developed therefrom.
