This paper presents an approach to design the sliding mode control for an AC-DC converter, consisting of a diode rectifier in series with a boost converter. The results obtained show that this converter with the proposed control law can be used to control the extraction of mechanical power when connecting the permanent magnet synchronous generator (PMSG) to a wind turbine. The boost converter operates in discontinuous conduction mode (DCM) in order to reduce the total harmonic distortion (THD) of the currents in the PMSG. To verify the performance of the proposed method, a simulation study is performed.
