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.
