Abstract :
The initial results from integration testing of the LHC magnet power converters revealed problems of low- frequency noise, settling time, drift with time and temperature, thermal management and EMC. These problems originated in the use of DSP, the A/D converter (ADC), the DCCT and their respective environments. This paper reports the methods used to improve the performance through hardware and software modifications and the results achieved.
