Abstract :
The China Spallation Neutron Source (CSNS) Rapid Cycling Synchrotron (RCS) injection system needs two pulsed power supplies to drive eight painting bump magnets which are connected as four horizontal painting bump magnets and four vertical painting bump magnets. The pulse current of the two pulsed power supplies are respectively 13832 A and 8205 A in phase-I, 17856 A and 10593 A in phase-II. The pulse current falling edge is made to work in a controlled manner. This paper will introduce the design of the pulsed power supply and the circuit simulation results.
