  The CERN Ac­cel­er­a­tor Com­plex con­sists of sev­eral gen­er­a­tions of par­ti­cle ac­cel­er­a­tors, hav­ing around 5000 power con­vert­ers sup­ply­ing reg­u­lated cur­rent and volt­age to nor­mal and su­per­con­duct­ing mag­nets. Today around 12 gen­er­a­tions of legacy con­trol sys­tem types are in op­er­a­tion in the ac­cel­er­a­tor com­plex, hav­ing sig­nif­i­cant im­pact on op­er­abil­ity, sup­port and flex­i­bil­ity for the con­verter con­trols elec­tron­ics. Over the past years a new gen­er­a­tion of mod­u­lar con­trols called RegFGC3 has been de­vel­oped by CERN's power con­ver­sion group. The goal is to pro­vide a new stan­dard­ised and cost ef­fec­tive con­trol so­lu­tion, sup­port­ing the largest num­ber of con­verter topolo­gies in a sin­gle plat­form. This will re­duce the main­te­nance cost by de­creas­ing the va­ri­ety and di­ver­sity of con­trol sys­tems whilst si­mul­ta­ne­ously im­prov­ing the op­er­abil­ity of power con­vert­ers. This paper de­scribes Thyris­tor-based power con­verter con­trols as well as the on-go­ing de­sign and re­al­iza­tion, fo­cus­ing on func­tional re­quire­ments and first im­ple­men­ta­tion.
