Design and Analysis of a Compact Single-Stage Cavity Combiner for the 20kw Solid State Amplifier Under Vacuum
Abstract:
Focusing on high-power acceleration systems for ultra-compact superconducting cyclotrons in special envi ronments, we aim to make breakthroughs in key technologies that restrict the improvement of high-frequency reliability for unattended accelerators. Research has been conducted on direct power syn-thesis technology and dynamic matching adjustment for solid-state power sources at the 20kW level. A dynamically tenable single-stage cavity direct power combiner based on a TEM cavity has been designed. High-frequency power signal flow calculations have been carried out for a system with 24 inputs and 1 output. Research has also been conducted on the impact of up to three module failures at arbitrary positions on the total output of the power source under different power combining circuit topologies, as well as corresponding compensation methods. It is expected to achieve iterative breakthroughs in key technologies such as lightweight high-frequency cavity high-power direct synthesis and adaptive power amplification circuit topology reconfiguration for solid-state power sources. An adaptive, highly redundant, lightweight solid-state high-frequency power source system for space applications will be developed.
