Control system and diagnostic tools for the TPS pulsed power supplies

The Taiwan Photon Source (TPS) is among the latest 3rd-generation 3-GeV synchrotron light source. Power supplies to control injection and extraction of the TPS pulsed magnets have been designed and implemented. Embedded Programmable Logic Controllers (PLCs) were developed to control the pulsed power supplies via the experimental physics and industrial control system (EPICS), which is remotely accessible with EPICS client tools. The timing system provides synchronous trigger signals for pulsed power supplies. Data acquisition systems with EPICS support are employed to observe the output current of the pulsed power supplies. The control system of these pulsed power supplies satisfies complete system integration, rich graphical user interfaces and useful diagnostic tools. It has been running without problems since mid-2014, which indicates its excellent reliability. A detailed description of the control system, operational interfaces, real-time monitoring system and diagnostic tools for the pulsed power supplies is presented in this paper.
