# 大功率整流系统运行损耗现场测试方法研究Study on the Field Test Method of the Operating Losses for High-Power Rectified System

Abstract: A field test method of the operating losses for high-power rectified system is proposed. This method is suitable for not only conventional rectified unit, but also new rectified unit which is com- posed of the new rectified transformer, the inductive filter and the rectifier. The topology of the new rectified system and its principle are described. On-site measurement method of operation loss for each component is given. The method uses many high-precision & portable power quality analyzer to synchronously measure the various components loss of the high-power rectified unit. The overall efficiency of the unit and the efficiency of the various components can be calculated. A detailed field test result for an industrial site engineering prototype is given to verify the correctness of the test method.
