High voltage high power klystron drivers using flexible solid state IGBT modules

In this paper we summarize the progress made in demonstrating the application of solid state switching to accelerator power systems. We discuss in considerable detail the development of a klystron drive system for an ion linac which uses a minimal number of IGBT components to produce average power levels of 60 kW-180 kW at 125 kV and peak powers of 7.5 MW.
