The study explores an induction motor drive system that combines a three-phase, reduced-switch modified Z-source inverter with an affordable induction motor. The modified Z-source system uses a four switch, 3Φ inverter other than a conventional 6-switch, 3Φ inverter, resulting in improved performance and reduced construction costs. The model replaces the capacitor leg with a DC-link capacitor and a specific LC network. Simulation results were analyzed and comparison done with the conventional 6 switch inverter. The modified Z-source inverter widens output voltage range, increases power factor and reliability, and decreases line harmonics.

摘要

The study explores an induction motor drive system that combines a three-phase, reduced-switch modified Z-source inverter with an affordable induction motor. The modified Z-source system uses a four switch, 3Φ inverter other than a conventional 6-switch, 3Φ inverter, resulting in improved performance and reduced construction costs. The model replaces the capacitor leg with a DC-link capacitor and a specific LC network. Simulation results were analyzed and comparison done with the conventional 6 switch inverter. The modified Z-source inverter widens output voltage range, increases power factor and reliability, and decreases line harmonics.
