Abstract :
The ring magnet of the injector synchrotron consists of 68 dipole magnets. Only one regulator circuit is used to control the firing pulses of the two sets of identical 12 phase power supplies that energize the magnets. PSPICE software was used to design and simulate the power supply performance under ramping and investigate the effect of current changes on the utility voltage and input power factor. A current ripple of +or-2*10/sup -4/ and a tracking error of +or-5*10/sup -4/ were needed.<>
