Abstract :
This paper discusses the use of hierarchical simulation models using the program Saber for the prediction of magnet ripple currents generated by the power supply/output filter combination. Modeling of an entire power system connected to output filters and particle accelerator ring magnets will be presented. Special emphasis is made on the modeling of power source imbalances caused by transformer impedance imbalances and utility variances. The effect that these imbalances have on the harmonic content of ripple current is also investigated
