FTU magnetic poloidal fields are powered by four dodecaphase bridges completely thyristors controlled also called Converters. Three of them are fed from MFG3 (AL-T , AL-V , AL-F) and one (AL-H) from the national electricity network.
Thyristors Converters convert alternate input voltage and current into direct voltage and current on the loads (which are FTU poloidal field magnetic coils) with profiles under control of regulation systems. One converter for each one type of FTU poloidal coils.
