By the end of the nineties, the Power Converter Control System of the SPS (Mugef) had undergone a complete modernization. This resulted in newly developed hardware for function generation, measurement and I/O in a VME environment under the LynxOS real-time operating system. This has provided a platform, on which extensions can be developed for future operation in the LHC era. This paper describes some of these extensions, in particular a fast Surveillance and Interlock system for monitoring the Power Converter output currents. This will be mandatory for the safe operation of the SPS transfer lines TI2 & TI8 to LHC and for the Neutrino beam to Gran Sasso. The strategies employed to cope with various failure modes of the Power Converters and the timely activation of the interlock are outlined. The new SPS controls infrastructure now under development, will give rise to new modes of operation for the Mugef systems. Integration with the Middleware of SPS-2001 must be undertaken in a structured evolution, whilst retaining compatibility with the current usage.
