摘要
A new inverter test method using back-to-back inverter power circulating strategy is presented in this paper. Using the method, high power test for traction inverter with wide power factor range can be achieved by selecting appropriate modulation scheme. The zero-sequence current issue inherent to the setup is investigated and addressed in order to improve the output current quality. Moreover, the similarities and the differences between the proposed setup and open-end winding motor drives are discussed. Experimental results verifying the high-power operation with wide power factor range achievable by the proposed method are provided.
