摘　　要：设计了一个非接触式电流谐波检测的综合实验,实验电路包括功率放大、互感线圈、电流-电压转换、有效值检测、程控滤波、单片机控制、现场可编门阵列(FPGA)分频和计数等.实验除了覆盖电子线路、FPGA等硬件课程外,还融合了信号与系统课程中的信号分解与合成的理论知识.设计方案注重新型器件的运用,为电子系统设计的实践教学提供了良好的案例.The implementation of China Engineering Education Accreditation promotes experimental teachers to incorporate knowledge points of many professional courses, subject contests, teachers’ accumulation of scientific research and modern electronic technology into the design of experimental cases. A comprehensive experiment of non-contact current harmonic detection is proposed. The experimental circuit includes power amplifier, mutual inductance coil, current-voltage conversion, RMS detection, programmable filter, MCU, FPGA frequency division and counting. In addition to covering courses such as Electronic Circuits and FPGA, it also incorporates theoretical knowledge of signal decomposition and synthesis in course of Signals and Systems. At the same time, the design focuses on the application of new devices. It provides a good experimental case for the practical course design of electronic system design.
