The MBA upgrade for the APS requires a large number of power supplies with either unipolar or bipolar DC output currents. The unipolar power supplies will be used to power the main coils in the dipole, quadrupole, and sextupole magnets and the bipolar power supplies will be used for the trim or correction coils. There are several demanding requirements of the power supplies. The unipolar power supplies are expected to have a current stability within 10 parts per million (ppm) of the full scale. The currents must be calibrated to the specification and confirmed with independent and accurate measurement. The bipolar power supplies for the fast correction magnets are required to have a wide output current bandwidth in order to minimize the impact on the real-time feedback system for the beam position correction. There are also new requirements for the power supply controls and communications that are much more demanding than that in the existing APS accelerators. This paper will report the conceptual designs of the power supply systems and the R&D program that is developed to find solutions to the technical challenges.

The MBA upgrade for the APS requires a large number of power supplies with either unipolar or bipolar DC output currents.
