摘　　要：提出基于空间矢量脉宽调制的P I直接转矩控制的交流测功机的测试方案。通过直接控制交流测功机的电磁转矩,自动调节被试电机的负载转矩,无需转矩仪可精确获得被试电机的电磁转矩,简单直观,动态响应快,可实现交流测功系统的四象限运行;并为被试电机提供了一个较理想的可控的试验电源。A new method was proposed on the basis of Space Vector Pulse Width Modulation and Direct Torque Controlled AC dynamometer based on PI regulators. The magnetic torque was directly controlled to regulate the load of motor under test in an indirect way, which can simply gain the precise value of magnetic torque of MUT without torque instrument and its dynamic performance is excellent .The dynamometer system can work steadily in four quadrant.
