摘要

给出了一种基于计算机的高分辨率电动汽车牵引逆变器效率测量系统的性能评价。首先进行仿真研究，确定电动汽车牵引逆变器效率曲线的上限。然后，完成了实验效率测量。在实验研究中，采用30kVA感应电机-测功机系统，获得1kW-8kW之间的负载。效率测量是用YOKOGAWA WT500功率分析仪和基于计算机的效率测量系统完成的。从精度和成本两方面对结果进行了讨论和比较。

Comparison of efficiency measurement techniques for electric vehicle traction inverters

Performance evaluation of a high-resolution computer based efficiency measurement system for electric vehicle (EV) traction inverter is given. First, a simulation study is carried out to determine the upper limit of the EV traction inverter efficiency curve. Then, experimental efficiency measurements are completed. In the experimental study, a 30kVA induction machine-dynamometer system is used to obtain the loading between 1kW-8kW. Efficiency measurements are completed with both the YOKOGAWA WT500 power analyzer and the proposed computer based efficiency measurement system. Results are discussed and compared considering the accuracy and the cost.
