Abstract :
In this paper, a three-level AC-DC-AC VSI (Voltage Source Inverter) with IGCTs (Integrated Gate Communicated Thyristors) used in pumps and fans was developed. The inverter structure has an uncontrolled rectifier with 24-pulse DC voltage output, and has a diode NPC (Neutral Point Clamped) three-level inverter with an LC filter to maintain a 6 kV sine wave voltage output. Results of simulation and experiment show that the designed system has high performance, reliability and availability.
