电流检测广泛应用于电力电子应用，包括 DC-DC 功率转换和可调速电机驱动，它们是混合动力汽车的基本子系统。系统的动态性能和控制取决于传感器的精度和效率。本文回顾并检验了几种电流传感方法。描述了传统方法，包括电流检测电阻器技术以及先进的自调整和自校准方法。基于其无损、简单和易于实现的特点，对各种方法进行了分析和比较。还考虑了高功率应用。
Current sensing is widely used in power electronic applications including dc-dc power conversion and adjustable speed motor drives, which are the basic subsystems of hybrid vehicles. Dynamic performance and control of the system depend on the accuracy and efficiency of its sensors. Several current sensing methods are reviewed and examined in this paper. Conventional methods including current sensing resistor technique as well as advanced self-tuning and self-calibrating approaches are described. Various methods are analyzed and compared based on their losslessness, simplicity, and ease of implementation. High-power applications are also considered.
