N2 - This paper mainly focuses on the space vector modulation (SVM) for the three-phase two-level inverter with delta-connected loads (TTDI). At first, the key features of TTDI, such as voltage vector distribution and common-mode voltage (CMV), are analyzed as the foundation. Accordingly, the basic SVM strategy for TTDI is presented referred to the conventional SVM for the three-phase two-level inverter with star-connected loads. Subsequently, to reduce the CMV during the operation, a CMV reduction-based SVM (RCMVSVM) is proposed for TTDI. In different modulation range, different voltage vectors are selected to modulate, and their sequences are well designed to reduce the CMV. From the simulation verification, it can be found that the amplitude of CMV will be suppressed to one-sixth of the dc-link voltage by the proposed RCMV-SVM. While the counterpart in basic SVM is half of the dc-link voltage, which demonstrates the effectiveness of the proposed RCMV-SVM strategy.
