摘要：

DC bus systems are utilized to deliver powers to various motor loads. Inverters are placed just before motors to give appropriate powers. When the inverters are controlled to output constant powers, they may have negative impedances at the DC input bus because of constant power characteristics. This may cause a stability problem due to interactions between the inverter impedances and DC filters. This paper proposes an analytical calculation method of DC input impedance of an induction motor drive system for stability analysis by the impedance method. The developed method considers the slip control, the decoupling control, and mechanical perturbations in the small-signal model. Analysis examples by the proposed method are investigated and validated analytically and experimentally. © 2022 The Institute of Electrical Engineers of Japan.
