Switching Ripple Harmonics Attenuation in DFIG and Matrix Converter-Based WECS

The analysis presented in this paper is focused on the harmonics distortion damping in the case of bidirectional power-flow of the electronics device—matrix converter as an interface between two power sources. Bidirectional energy flow takes place in the matrix converter that is used in renewables,...
