Description

In order to minimize the latency of Sirius Fast Orbit Feedback (FOFB), a 12-channel current source power supply was designed as a μRTM module. Each chan­nel consists of a linear am­pli­fier operating as current source by means of a digital feedback loop implemented on an FPGA at the AMC board. The am­pli­fier is spec­i­fied to reach up to 10 kHz small-sig­nal band­width on a 3.5 mH in­duc­tance mag­net and ±1 A full scale. This work will re­port on the performance figures obtained prior to releasing the design for final production.
