Abstract
In this paper, a voltage and current control scheme of a three-phase voltage source inverter for UPS is described. The inverter provides pure sinusoidal output voltage with very low THD(Total Harmonic Distortion). The proposed controller is designed to robust against the load change, parameter variations, and disturbances using PI controller. The switching pattern is determined to Space Vector Modulation. Finally, the performance of the proposed inverter is shown and discussed by simulation.
