Series Z-source inverter fed motor drive

The Z-source inverter (ZSI) has single state power conversion capability with buck-boost ability. Series Z-source inverter (SZSI) reduces inrush current, resonance between capacitor and Z-inductor and stress on capacitor. This paper presents a simple technique to increase shoot through in SZSI. The major benefit of this technique is improved performance of inverter in terms of boosting and harmonics profile. The validity of proposed technique is verified through simulation.
