Quasi Z-Source Neutral-Point-Clamped Inverter Using SVM Technique to Eliminate Common Mode Voltage

In recent year, common mode voltage (CMV) elimination methods are considered to improve the reliability of three-level quasi-switched boost T-type inverter (TL-qSBT2I). The space-vector modulation method (SVM) can control operation eliminate CMV. proposed applies medium vectors and zero vector synthesize reference CMV while output is unchanged compared SinPWM technique. order prevent active from being affected, shoot-through inserted inside vector. Accordingly, not only maintains advantage SVM technique for TL-qSBT2I but also reduces inductor current ripple enhances gain without any topology modification or adding electrical components. Results simulations experiments used evaluate efficiency suggested strategy. Additionally, by comparing scheme with traditional pulse-width technique, superiority shown.
