In this paper, a space vector pulse-width modulation (SVPWM) control scheme for the three-level quasi-switched boost T-type inverter (TL-qSBT2I) to reduce common mode is presented. The magnitude and slew rate of common-mode voltage (CMV) are reduced by using the proposed method. By properly selecting the shoot-through (ST) phase, the ST states are inserted within a small vector so that the active states and output voltage are unchanged. In this method, the ST duty cycle is kept constant to obtain the modulation index as high as possible while the duty cycles of the two additional switches are the control variables. The proposed method can mitigate the peak value of CMV up to 50% and the RMS value up to 35.3% as compared to the conventional SVPWM control method. To verify the operating principle of the TL-qSBT<SUP>2</SUP>I, the simulation and experimental results are shown.
