| Popis: | In this paper we describe the modifications of power supplies needed to operate the storage ring with a low momentum compaction factor (low alpha) to generate short x-ray pulses. This design includes an external polarity reversal circuit in quadrupole and sextupole magnet power supplies. The polarity reversal circuit contains four relay module where each relay can receive signals from the D-type analog interface. The power supply control system must be enhanced to switch output polarity. The operating principle and analyses of polarity reversal are discussed in more detail. Finally, a prototype polarity reversal circuit with 30 V, 250 A and 7.5 kW output power is implemented in the laboratory to verify the expected performance for the TPS low alpha operation.
