摘　　要：对功率模块进行全功率测试时,若采用直接驱动负载的方式,需要搭配大容量的电源和负载,试验条件苛刻。采用纯电感负载三相逆变对拖的全功率测试方法,通过控制对拖的2个逆变电路输出电压相位差,调节负载电流的大小,能够降低对试验电源和负载的要求。该测试方法通过仿真验证了可行性,并在搭建的试验台上进行了模拟应用。In a full power test for power modules,if the load is directly driven,a high capacity power supply and load are required,and the test conditions are harsh.The pure inductive load three-phase inverter back-to-back full power test method can reduce the requirements for the test power supply and load by controlling the phase difference of the output voltage of two inverter circuits and adjusting the load current.The feasibility of the test method has been verified through simulation and the method has been applied to the built test bench.
