摘要
大型聚变装置中国环流器2号A(HL-2A)中脉冲高压电源具有功率大、电磁环境恶劣、上升时间快的特点;根据电源特点测量系统除了监测电源工作波形,还要为检测系统、控制系统提供实时数据;高压信号传输采取的是基于压频转换的光纤隔离技术,并且将此技术与DSP相结合,实现压频(V/F)型A/D转换的方式,简化了线路,提高了抗干扰的能力。这种传输方式线性度好,对温度不敏感、抗干扰能力强、响应时间比较快(50μs),并且结合实验中电源异常现象通过测量参数波形加以分析、排除,具有很高的实用性;实验证明该测量系统具有真实反映电源工作波形的能力,及为监测及控制系统提供了实时数据的能力。
The pulse high voltage power supply with power in china large fusion devices HL--2A is characteristic of poor electromagnetic environment and fast rise time. According to the power characteristics, in addition to monitoring the system power supply waveform, but al- so real--time data is provided for the detection system and the control system from measurement systems. Voltage to frequency converter based on fiber isolation technology is adopted for high voltage signal transmission, Voltage to frequency （V/F） --type A/.D conversion means is achieved through the combination of the technology and DSP, which simplify the circuit and improve the ability of anti--jamming. This transmission linearity, temperature insensitive, anti--interference ability, response time is faster （50μs）. Anomalies with the experi- ment by measuring the waveform parameters of the power are analyzed with high practicality. Experiments show that this system is good true reflection of the ability of wave power supply, and provide real--time data for the monitor and control system.
