Abstract:

A 100kV/60A high voltage power supply (HVPS) is being developed to carry some auxiliary heating research on J-TEXT and supply the auxiliary heating system. The power supply which consists of 144 switch modules is based on PSM technology. For the requirement of isolation, control and protection, a control system based on the PCI extensions for instrumention (PXI) which meets up with the CODAC standards is designed with developed PSM technology for the high voltage power supply. The compact structure of hardware in the control system is presented too. And the control strategy which is based on shift phase pulse width modulation is discussed Some tests are performed on the control system to validate the control strategy, the experimental results show that the system has a good control performance and fast response, which meets the control requirement of 100kV/60A high voltage power supply.

Key words: HVPS, PSM, Control, PXI, FPGA

摘要:

介绍了J-TEXT装置上将用于辅助加热研究的一套100kV/60A高压电源。这套高压电源基于PSM技术设计,由144个开关电源模块构成。为了满足隔离、控制和保护的要求,采用PXI和FPGA技术设计了符合CODAC规范的PSM电源控制系统,并提出改进的PSM控制策略实现对高压电源的控制。为验证控制系统的性能,在由8个模块组成的高压电源模型样机上对控制系统进行了测试,测试结果表明,系统各项性能良好,可以满足100kV/60A高压电源的控制要求。
