Double-loop stabilization system of output voltage of high-voltage power supply for powerful travelling wave tube

摘要

The paper describes schemes to stabilize of the output voltage of the high-voltage power supplies for the powerful traveling wave tubes. It is shown that the considered schemes provide the reliable power supply of the delay system of the traveling wave tube in complementary sets of load conditions and conditions of changing parameters of the mains. However, none of these schemes provides the reliable power supply in whole set of conditions. So the double-loop stabilization system that combines both methods of control which used in the considered schemes is proposed. The coordination of the work of loops is realized by using the fuzzy controller. The simulation results and the experimental research demonstrate the advantage of the proposed system in whole set of conditions and across all efficiency indicators.
