Power Density and Reliability Metric Assessment of Thyristor Controlled Rectifiers for AES

This paper presents a robust design strategy followed by pertinent metrics production for a twelve pulse thyristor controlled rectifier (TCR) specifically for medium voltage DC systems (MVDC) in all electric ships (AES). System level design exercises through a full factorial design method have been used to identify the most suitable parameters for a power dense and reliable converter. An approach to deriving scaling relations for converter parameters with associated output metrics are presented in this paper. Outcomes are expected to enhance early stage ship design studies through the development of the Smart Ship Systems Design (S3D) environment.
