摘要：

This work proposes a novel circulating current control using sliding mode control (SMC) and modified space vector modulation (SVM applied to the two inverters connected in parallel for the induction motor (IM). The system these inverters control uses the field-oriented control (FOC) method. This configuration allows power segmentation and operation in degraded mode. However, a significant drawback is circulating currents between the inverters. The study analyzes and models the parallel system's zero-sequence circulating current (ZSCC) and cross-current paths. Therefore, the design of the control algorithm must ensure the reduction of circulating current while ensuring stability, reliability, efficiency, and performance improvement. Simulation results have validated the effectiveness and performance of the proposed modulation and control strategy.
