High reliability high voltage power processors

Design and performance summaries of several aerospace TWT power processors are presented in this paper to illustrate key design concepts, key features and circuit highlights. Output voltages up to 20 kV and DC power levels up to 1 kW are discussed. The usage of the entire gamut of power processor building blocks are described, including linear and switching-mode regulation and energy-storage, self-saturating and PWM converters. Also described are the component selection and packaging techniques used to obtain ultra-high reliability systems.
