The Power Supply Technology Group concentrates on the development, operation, and maintenance of specialized power supply systems for accelerators. Currently, the group has 25 staff members, including 3 principal senior engineers and 9 associate senior engineers, with 92% holding a master's degree or higher. 

The power supply system is a critical component of accelerator systems, providing high-precision excitation currents for magnets. Its performance directly determines the quality of the particle beam.

The Power Supply Technology Group possesses strong capabilities in the research, development, operation, and maintenance of specialized accelerator power supplies. The group has developed power supply systems for major national scientific facilities such as HIAF and HIRFL-CSR, and is responsible for their operation and maintenance. Additionally, the group has undertaken the development of power supply systems for collaborative projects, including the SIMM cancer treatment device, the PREF and the SESRI system.

The Power Supply Technology Group primarily focuses on the following research areas: Power Electronics, Analog and Digital Control Technologies, Pulse Power Technology, Process and Reliability, and Electromagnetic Compatibility. The main types of power supplies developed include conventional DC power supplies, high-power pulse power supplies, BUMP power supplies, scanning power supplies, high-voltage DC power supplies, and high-voltage pulse Kicker power supplies, among others.
