Digital control system for high precision power supplies of the new Brazilian synchrotron source

Abstract

This paper proposes an architecture of digital current regulator intended to be used to control the power supplies of the new Brazilian synchrotron light source, called Sirius. It is based on a high-precision Digital to Analog Converter and a modern System on Chip device, which has the capability of performing realtime control tasks together with managing and interface tasks. Despite this system will be used to control many kinds of power supplies, it was validated in a 100 W power supply, which was previously developed to be used in the present Synchrotron Light Source.

2-Hz ramping mode magnet power supply for particle accelerators

“…The goal is to have equipment to test the dipole magnets and to verify the behavior of two modules operating in parallel, already reaching the final current of 1kA. This second prototype must use the Digital Regulation System (DRS) developed by LNLS [10] instead of the analog system, bringing better results than the previous one.…”

“…Outros trabalhos têm se proposto ao desenvolvimento de modelos do sistema no espaço de estados, técnicas de identificação e modelagem clássica por função de transferência. (de Oliveira, 2018;da Silva Lima, 2019;Brunheira et al, 2013).…”
