The Spallation Neutron Source (SNS) started operations in 2007 after extensive equipment commissioning. Electrical Power Conversion (EPC) equipment was originally specified or designed by different national laboratories and manufactured by various vendors. The equipment includes Low Energy Beam Transport (LEBT) chopper pulsers, High Voltage Converter Modulators (HVCMs), DC magnet power supplies, and injection and extraction kicker power supplies. Miscellaneous issues caused lengthy down time in the beginning, but the issues have been resolved through many prioritized upgrades and improvements. EPC equipment availability reached 98% in 2011 and has remained high. This presentation will discuss the past operation history and the current equipment status. Ongoing and future upgrades will also be discussed.
