The Australian Synchrotron storage ring consists of 28 dipoles, 56 focusing quadrupoles, 28 defocusing quadrupoles, 98 sextupoles, 42 horizontal correctors, 56 vertical correctors and 28 skew quadrupole correctors. The 28 dipole magnets are series connected and powered by a single 1100V, 850A, 24 pulse power supply with an output stability better than 100ppm. The paper will discuss the design, testing, commissioning and control interfaces for the storage ring dipole power supply.

As high frequency switching solid state devices are replacing tube devices and linear devices, power systems become more compact and modular. In those systems, it is desirable to have a high quality and multi-function control board per each power system module. In order to maintain reliable operation of the power system module, the control board requires having multiple and complex functions. Moreover, the control board needs to be compact and low power consuming. It also needs to have a fast communication with the main control station. However, there is no such control board available commercially. Therefore, a general purpose power system control board (PSCB) has been under development since 2005 as a collaboration effort between PAL and SLAC. The PSCB is an embedded, interlock supervisory, diagnostic, timing, and set-point control board. It is designed to use in various power systems such as sequenced kicker pulsers, solid state RF modulators, simple DC magnet power supplies, etc. The PSCB has the Ethernet communication with the TCP/IP Modbus protocol. This paper will describe detail functions and preliminary test results of the PSCB.
