Abstract :
The overpass power supply system consists of two power supplies. A 1 kV, 3600A SCR supply drives eight Main Ring type magnets and must track twice the Main Ring current to within ±0.1%. The second supply drives trim coils wound inside four of the main magnets. This dual-converter SCR supply, a modified Fermilab H. O. P. S. unit,1 supplies ±50A at ±30V and it must generate ±200V swings to buck-out the voltage inductively coupled from the main supply. Both power supply regulators use dead reckoned voltage drive programs to extend their effective bandwidths.
