摘要
电源部分是超声导波检测系统的关键组成部分,良好的电源设计能为运放电路提供稳定、高效的电源保障,确保检测数据的可靠性和准确性。本实验对Linear公司推出的LTC3872电源芯片进行研究,完成了以FPGA为核心的超声导波检测设备的脉冲功率电源系统的设计,测试结果表明,系统工作稳定,电气参数符合预定的要求,为超声导波检测系统的小型化打下良好基础。
The power supply＇s the key part of the detection system. Excellent power system can provide not only stable and efficient power supply,but also can ensure the inspection data dependability and veracity. This paper provides some research on LTC3872 power chip produced by Linear inc and completed pulse power system design of guided wave testing system based on FPGA. Test displayed that system can work steadily, electric parameter accord with expectant demand, and lay a good foundation for the miniaturization of the ultrasonic guided wave testing system.
