A DCM three-phase SEPIC converter for low-power PMSG

Abstract

A new three-phase controlled converter for low-power PMSG is presented in this digest. The converter is a SEPIC one, operating at DCM. The topology incorporates the PMSG inductance as its input inductor, and the generator currents are almost harmonics-free. Design equations are also presented, and results from simulations for both high and low wind speed show that this topology has a strong potential in the proposed application.
