Abstract
In this paper, control scheme of the three phase VSI(Voltage Source Inverter) for 200KVA UPS is described. The proposed controller is designed to robust against parameter variations, disturbances and load change using PI controller. The switching pattern is determined to Ramp Comparison Method. The inverter provides pure sinusoidal output voltage with very low THD (Total Harmonic Distortion). Finally, the performance of the proposed inverter is shown by experimental result.
