脉冲阶梯调制高压电源快恢复技术
Fast recovery technology for pulse step modulated high voltage power supply
摘要
Abstract
Neutral beam injection heating is an effective heating method in magnetic confinement fusion experiments.If the ion source ignites during experimental operation,the extraction of the ion beam is terminated,reducing the efficiency and power of the neutral beam ion source beam extraction.To prolong the extraction of the ion source beam in case of abnormal situations,research on high-voltage power fast recovery technology was carried out,in which the beam was re-extracted by running the high-voltage power supply again.A fast recovery control system was developed based on PXI Express technology,using the PXIe-8861 processor and PXIe-7820R programmable logic gate array hardware board for fast recovery technology.The control system adopts a heartbeat packet mechanism for board and communication status monitoring,with two parameter configuration methods for client and upper computer,realizing the functions of online/offline data viewing and analysis.Through the configuration of the upper computer mode,the control system supports voltage and quantity control,meeting multiple working modes such as modulation,fast recovery,and single operation.Test results on a megawatt-class strong ion source show that the control system interface is user-friendly,the logical structure is designed clearly,and it has various control modes.Furthermore,the system can restart the high-voltage power supply to improve the extraction power of the ion source beam during the experiment.关键词
