Analysis of DC Converters forWind Generators

The present paper investigates the system behavior of a rectifier and a DC-boost converter used in a wind generator with variable speed. In many cases a combination of diode rectifier and a DC boost converter is used as interface between the generator and the inverter in order to match the requirements fo r the DC bus voltage. Different models of the converters have been developed in Malab/Simulink and PSPICE environments. Comparison between the simulations and experiments is shown. The power losses are also discussed.
