The world's first! Breaking through multiple core technology pulses | Power supply | Global
The reporter learned from the Institute of Modern Physics of the Chinese Academy of Sciences that on July 7, the international first large-scale non resonant full energy storage fast cycle pulse power supply developed by the Institute of Modern Physics of the Chinese Academy of Sciences and other units passed the on-site test of the expert group.
The high current heavy ion accelerator device is a national "Twelfth Five Year" scientific project built under the auspices of the Institute of Modern Physics of the Chinese Academy of Sciences. The intensifier BRing is the core component of the device. The special pulse operation mode of the BRing bipolar iron power supply will generate great energy throughput in the ascending and descending sections of the current pulse waveform, which will have a huge impact on the power grid and pose an unprecedented challenge to the power system design.
In view of the strict requirements of the high current heavy ion accelerator device, the accelerator team of the Institute of Modern Physics of the Chinese Academy of Sciences innovatively proposed a solution for the full energy storage of the front excitation of the non resonant transformer. After four and a half years of concentrated research, 41 technical problems were solved, breakthroughs were made in four core technical problems, and the problems such as the periodic strong impact of the high-power fast cycle pulse power supply on the power grid and the requirements for high-precision output indicators under an extremely wide voltage range were well solved. After entering the mass production stage, the power supply continuously iterated and optimized the process plan, achieving modular, integrated, and standardized design of the power supply, greatly improving its reliability, maintainability, and electromagnetic compatibility. On July 7th, the first power supply product in the mass production stage of the power supply was taken offline and passed on-site testing by an expert group. This marks another solid step in the construction of high current heavy ion accelerators.
The successful development of high-power non resonant, variable excitation, and full energy storage pulse power supplies has made it possible for large-scale accelerators to operate in a green and low-carbon manner. It has broad application prospects in heavy ion cancer treatment devices and other applications, and also provides a new implementation scheme for special pulse power supplies for world large-scale accelerators.
