内容記述 | Next-generation synchrotron radiation sources, such as SPring-8 upgrade, require various kinds and large amounts of magnet power supplies, and most of them are require to be highly stable. In order to provide many power supplies with a reasonably low cost in a short production period, we developed a common current control system using a digital feedback control technology. The system consists of a high-precision analog-digital converter (ADC) circuit and a feedback controller using a field programmable gate array (FPGA). We tested a DC power supply equipped with the above digital feedback control system, and confirmed that the current ripple could be suppressed to less than 5 ppm (pk-pk). We also prototyped a high power DC power supply with 650 A based on a modularization concept. We also prototyped a DC-link power supply for a steering magnet with synchronized current output between 3 ports. | |||||
