Abstract

This paper will describe the preliminary design of a 4.8 MW Main High Voltage Power Supply, rated 60kV/80A, especially conceived to supply the voltage between Cathode and Collector of a Gyrotron. A full solid state technology, named SWM (Stair-Way Modulation) for the full scale Electron Cyclotron (EC) Test Facility at CRPP, Lausanne. The ITER EC system may also make use of a similar system, in alternative to the present baseline design based on naturally commutated thyristor converters and series high voltages solid state switches. The 60kV output is reached by adding more than 120 high voltage modules in series connection, with ad hoc control criteria to allow a regulation at full performances in the range of 45kV-60kV, a square wave modulation and a fast switch-off in less than 10us. Components choices and simulations of the system will be highlighted in order to demonstrate the fulfilments of the technical specification before the manufacturing stage. This solution can be extended to several applications in the High Voltage domain and is aimed to enhance the reliability, decrease costs, provide redundancy, plug-in modularity, component de-rating and component standardization.
