摘要：

The suppressor grid power supply has been developed in the neutral beam injector (NBI) for the experimental advanced superconducting tokamak (EAST). Being an important part of NBI's power supply system, the suppressor grid power supply will deliver a high dc voltage at the suppressor grid. It mainly consists of a thyristor voltage regulator, a bridge rectifier, an LC filter, a fast switch and the control and protection circuits. Given the operation characteristics of the power supply, the corresponding requirements and specifications are described. Later on, this paper basically introduces the circuit structure, the control and protection methods and the fast switch technology. Some ratated test results and the operation results are also presented, which verified the performance of the power supply.
