Abstract
This paper investigates the suitability and experimental testing of a simple power converter for a permanent magnet generator for use with a small-scale variable-speed wind turbine. The controller uses a switched-mode rectifier in conjunction with a high inductance generator that allows generator torque and power to be controlled via the switch duty-cycle. The controller maximises output power for wind speeds below rated, and limits turbine speed for higher wind speeds. Dynamometer and limited wind turbine test results are presented.
