The MedAustron accelerator is a synchrotron for light-ion therapy, developed under the guidance of CERN within the MedAustron-CERN collaboration. Procurement of 7 different power converter families and development of the control system were carried out concurrently. Control is optimized for unattended routine clinical operation. Therefore, finding a uniform control solution was paramount to fulfill the ambitious project plan. Another challenge was the need to operate with about 5'000 cycles initially, achieving pipelined operation with pulse-to-pulse re-configuration times smaller than 250 msec. This contribution shows the architecture and design and gives an overview of the system as built and operated. It is based on commercial-off-the-shelf processing hardware at front-end level and on the CERN function generator design at equipment level. The system is self contained, permitting use of parts and the whole is other accelerators. Especially the separation of the power converter from the real-time regulation using CERN's Converter Regulation Board makes this approach an attractive choice for integrating existing power converters in new configurations.
