摘要
以TMS320F2812为控制芯片介绍了双向电流检测的3种方法:电压提升法、绝对值电路法和新型双极性AD芯片法。它们不仅能够检测电流的大小,而且能判断电流的方向。通过实验证明了这3种方法都能精确地检测双向电流,并给出了各方法的优缺点。
Three methods of bi- directional current detection based on control chip TMS320F2812 were discussed：the voltage boost method,the absolute value circuit method and the new bipolar AD chip AD7321 method. They can detect not only the current value, but also the direction of the current. It was experimentally proved that these three methods can accurately detect bi - directional current. Both their advantages and disadvantages were demonstrated.
