Description
Focusing on high-power radio-frequency systems for ultra-lightweight high-temperature superconducting cyclotrons in special environments, we aim to make breakthroughs in key technologies that restrict the improvement of radio-frequency system reliability for highly automated cyclotrons. Research has been conducted on direct power combining technology and dynamic matching adjustment for solid-state power amplifiers at the 20-kW level. A dynamically tunable single-stage cavity direct power combiner based on a TEM cavity has been designed. Radio-frequency power signal flow analysis has been performed for a system with 24 inputs and one output. Research has also been conducted on the impact of up to three module failures at arbitrary positions on the total production 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 ultra-lightweight high-power radio-frequency cavity direct synthesis and adaptive power amplification circuit topology reconfiguration for solid-state power sources. This paper reports an adaptive, highly redundant, and lightweight solid-state radio-frequency power amplifier system designed for space applications.
