1.1 Model 05100PS-430-601 Integrated Power Supply System Fea-
tures
The AMI Model 05100PS-430-601 High-Stability Power Supply System is
a sophisticated digitally-controlled power supply which allows an operator
to manage a superconducting magnet system with unprecedented
accuracy and ease of use. Integral components of the system include a
Model 430 Programmer with zero flux current sensing system, Model 601
Energy Absorber, and Model 08150PS Power Supply. The AMI Model
05100PS-430-601 Power Supply System provides for a degree of flexibility
and accuracy previously unavailable in an economical commercial product.
1.1.1
Digitally-Controlled
The Power Supply System is controlled by a microcomputer-based control-
ler which controls all analog data conversion, display/keypad functions,
communications I/O, generation of analog programming signals for the
external power supply, and control law computations. The Power Supply
System incorporates digital signal processing (DSP) functions that provide
for accurate control, low drift, and flexibility of use.
1.1.2
Superior Resolution and Stability
The Model 430 Power Supply Programmer incorporates high-resolution
converters to translate signals between the analog and digital domains.
Precision instrumentation techniques and potentiometer-free designs are
employed throughout the Model 430 Programmer to ensure accurate sig-
nal translation for a wide range of conditions. The magnet current is sam-
pled at 24-bit resolution in hardware and is software-programmable to 15-
digits resolution. All pause and hold functions are performed in the digital
domain which provides for excellent stability and drift of the programmed
magnetic field.
For greater stability and accuracy, the Model 430 Programmer is config-
ured with a zero-flux precision current measuring device instead of the
standard resistive shunt. This option typically increases the system stabil-
ity and accuracy by an order of magnitude. The power supply systems
incorporating this technique are referred to as “high-stability” systems.
1.1.3
Intuitive Human-Interface Design
The Power Supply System was designed to simplify the interface where
possible. All functions were analyzed and subsequently programmed so
that the most commonly used functions are addressed with the least
