Converter Regulation Board Status

The Converter Regulation Board (CRB), detailed by Ph. Fraboulet, is pivotal for regulating current in magnets. This 3U x 200 mm electronic board incorporates a DSP core for efficient regulation, high-precision analogue acquisition for both current and voltage, and a communication interface with the PCC via FED. Key tasks include defining links between CRB and PCO/PCC, ensuring precision for current regulation, and developing a trigger interface for PCO control. Key documents will elaborate requirements, interfaces, and specifications, with design schematics expected by year-end. Progress includes PCB routing, prototype manufacturing, and validation steps leading towards improved B-field measurement and temperature regulation.
