| The Shanghai Synchrotron Radiation Facility (SSRF) is a third-generation synchrotron radiation light source under construction. In SSRF, there are 520 sets of magnet power supplies for the storage ring and 163 sets for injector. All of the power supplies are in PWM switched mode with IGBT. A high precision stable output power supply for 40 dipoles rated at 840A/800V with the stability of ±2·10-5/8hrs will be used for storage ring. 200 sets of chopper type power supply will be used for exciting main winding of quadrupoles respectively. In booster ring, two sets of dynamic power supply for dipoles and two sets for quadrupoles will run at the biased 2Hz sinusoidal wave. All above power supplies will work with digital power supply controllers designed by PSI. All power supplies are being manufactured at professional power supply companies in China. |
