Abstract A novel space vector modulation (SVM) strategy called maximum-boost discontinuous SVM (MBDSV) is proposed in this paper to reduce the thermal stress of three phase impedance source inverters (ISI). By exploiting the switch clamping mechanism and arranging the shoot-through (ST) states properly, the proposed strategy obtains the flowing merits: further optimize the thermal performance, improve the reliability, reduce the current stress and maximize the dc-link utilization of ISI. The proposed MBDSV was compared to the existing modulation strategies and the feasibility of the MBDSV had been benchmarked by simulation and experiments.

三相阻抗源逆变器的热优化非连续调制策略

摘要 本文提出了一种新的空间矢量调制（SVM）策略，称为最大升压不连续支持向量机（MBDSV），以减少三相阻抗源逆变器（ISI）的热应力。通过利用开关钳位机制和适当安排直通 (ST) 状态，所提出的策略获得了流动的优点：进一步优化热性能，提高可靠性，降低电流应力并最大化 ISI 的直流链路利用率。将提议的 MBDSV 与现有的调制策略进行了比较，并且 MBDSV 的可行性已经通过模拟和实验进行了基准测试。
