Abstract
Abstract An upgrade is being conducted on the Tokamak a Chauffage Alfven Bresilien (TCABR), which is a small tokamak (R0 = 0.62 m and a = 0.2 m) operated at the University of Sao Paulo, Brazil. An important part of this upgrade is the installation of additional poloidal field coils to allow for the generation of various divertor configurations, such as single-null, double-null, and snowflake divertor. The control of these various magnetic configurations requires the development of 17 robust and high-performance power supplies. To identify the most appropriate solution, thyristor-based and IGBT full-bridge converter are being considered as possible power electronic topologies. In this work, a comparison between these two topologies in terms of controllability and complexity is presented.
