TI - The Progress of 300 kW Home-Made Fully Solid-State Transmitter for TPS J2 - Proc. of IPAC2021, Campinas, SP, Brazil, 24-28 May 2021 CY - Campinas, SP, Brazil T2 - International Particle Accelerator Conference T3 - 12 LA - english AB - To support the stable operation of Taiwan Photon Source (TPS) with 500mA beam current and the in-creasing beam line construction, a 3rd RF plant is thus constructed for such demand. The RF power source of the other 2 RF plants adopts klystron type transmitter and the 3rd RF plants is transferred to new technology of solid-state for better redundancy and easier mainte-nance. Base on the success of solid-state power ampli-fier development in 2020, a 3rd RF power source is thus decided to be made in house by solid-state tech-nology. The 500MHz 300kW solid-state transmitter is constructed by 4 80 kW solid-state power amplifier (SSPA) towers and power combined by 3 WR1800 3-dB hybrid couplers. Each tower is consisted of 110 850W final stage SSPA modules with 4 100W pre-amplifiers and 6 600W drive amplifiers. The pre and drive amplifiers are power combined for higher redun-dancy. The DC power are economical industrial 48V AC-DC rack mount power supplies which are parallel connected for higher total DC power and best redun-dancy. The architecture and present progress are pre-sented in this article.
