This paper focuses on the analysis and the design of a power electronic conversion system with reference to wind offshore applications. The proposed conversion system consists of a 6-phase AC-DC converter based on the SiC power semiconductors, to be used to control the achievable power from the wind turbine electrical generator. This system is suitable for applications where reliability and fault tolerance capabilities are the main targets. Voltage and current ratings have been determined to select the power module; furthermore, the analytical analysis to estimate the DC-bus rms current and voltage ripples is carried out. After that, the power loss equations have been derived in order to estimate the efficiency of the conversion. To validate the proposed hardware design, analytical results have been compared to simulation ones using Plexim/PLECS tool in Matlab/Simulink environment.

Abstract

This paper focuses on the analysis and the design of a power electronic conversion system with reference to wind offshore applications. The proposed conversion system consists of a 6-phase AC-DC converter based on the SiC power semiconductors, to be used to control the achievable power from the wind turbine electrical generator. This system is suitable for applications where reliability and fault tolerance capabilities are the main targets. Voltage and current ratings have been determined to select the power module; furthermore, the analytical analysis to estimate the DC-bus rms current and voltage ripples is carried out. After that, the power loss equations have been derived in order to estimate the efficiency of the conversion. To validate the proposed hardware design, analytical results have been compared to simulation ones using Plexim/PLECS tool in Matlab/Simulink environment.
