摘　　要：根据汽车变速器电控单元(TCU)的测试需求,研制了一套基于电力电子变流器的负载模拟系统。该系统根据不同型号TCU所配置的负载参数建立负载的离散模型,实时计算并运用电力电子技术跟踪负载状态,从而模拟多种类型的负载。实验证明,该系统具备模拟TCU常用无刷直流电机(BLDCM)型负载的能力,并且负载参数可实时调整,大幅增加了TCU硬件在环测试的灵活性和通用性。A load emulating system based on power electronic convert is developed in this paper.The discrete model of load is built under the load parameters configured by different TCUs.The load status is tracked by means of real time calculation and the power electronics technology to simulate multiple types of loads.Experiments show that the system is capable of simulating the commonly used brushless DC motor（BLDCM） type load of TCU,and the load parameters can be adjusted in real time.
