Abstract :
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.
