摘要
简要讲述了如何对交流变频调速系统中电动机定子电流进行有效检测,并详细介绍了利用FPGA实时控制两片A/D转换器AD1674以及利用FPGA实现对A/D转换结果的数字滤波。
It is simply presented that how to effectively measure the motor＇s stator current in AC variablefrequency speed regulating system. The real control for two AD1674 converter and the digital filtering for realizing A/D converter results by using FPGA are demonstrated in detail.
