Table 1 Assorted Data from Spice Model – “Girder” Booster Power Supply #1 Measurement: SPICE In an attempt to validate this simulation with the Booster Power Supplies, Voltage to Ground existing data was Booster Power Supply #1. supplied for An equation was fit to both the positive terminal to ground voltage and the negative terminal to ground voltage. The data is given in Figure 7 on the next page. The signals are taken from the magnet side of the power supply filter . A difference voltage was produced from this fit data. Assuming the booster current is in phase with this voltage data, the energy out of the supply was calculated. Since 12 each power supply drives the power per girder “Girders” 26,600 Watts. was determined to be This compares well to 25,810 Watts 15 Hz. the model loss of at Figure 7
