Design issues in a medium-voltage DC amplifier with a multi-pulse thyristor bridge front-end

Abstract

In this paper the design issues of a medium-voltage DC amplifier with a multi-pulse thyristor bridge front-end are presented. A medium voltage dc amplifier is needed in de-risking new technologies coming onboard future electric ships. Based on the required system dynamic specifications, an initial design reveals the problems with a multi-pulse thyristor front-end, and then provides a novel solution to meet the requirements, are presented. The proposed system solution is validated through both simulation and experimental results.
