On July 7, the world's first large-scale non-resonant full energy storage fast-cycle pulse power supply developed by the Institute of Modern Physics, Chinese Academy of Sciences and other units passed the field test of the expert group.

The world's first! Breakthrough in multiple core technologies!

The high-current heavy ion accelerator device is a national "12th Five-Year" scientific project hosted by the Institute of Modern Physics, Chinese Academy of Sciences. The booster BRing is the core component of the device. The special pulse working mode of the BRing diode iron power supply will be in the The rising and falling sections of the current pulse waveform produce huge energy throughput, which has a huge impact on the power grid and poses unprecedented challenges to the power system design.

In response to the stringent requirements of the high-current heavy ion accelerator device, the accelerator team of the Institute of Modern Physics, Chinese Academy of Sciences innovatively proposed a non-resonant variable front excitation full energy storage solution. After four and a half years of intensive research, 41 A technical problem, breakthroughs have been made in four core technical problems, which have well solved the periodic strong impact of high-power fast-cycle pulse power supply on the power grid and the high-precision output index requirements under an extremely wide voltage range. After the power supply entered the mass production stage, iteratively optimized the process plan, realized the modularization, integration and standardized design of the power supply, and greatly improved the reliability, maintainability and electromagnetic compatibility of the power supply.

On July 7, the first power supply product in the mass production stage of the power supply rolled off the assembly line and passed the on-site test of the expert group. This marks another solid step forward in the construction of the Intensive Heavy Ion Accelerator.

The successful development of high-power non-resonant, variable pre-excitation, and full energy storage pulse power supply makes it possible for large-scale accelerators to operate green and low-carbon. It has broad application prospects in heavy-ion cancer treatment devices and other applications, and is also a special Pulse power supply provides a new realization scheme.
