Experiment on Three-Phase Inverter with Output LC-filter under Unbalanced load Conditions using Robust Control

This thesis presents a robust control technique for three-phase LC-filtered inverter under unbalanced load conditions. Under unbalanced load cases, the output voltage becomes unbalanced due to the presence of negative sequence voltage. To obtain a well-balanced three-phase voltage, the negative sequence must be eliminated. Therefore, a paralleled voltage control is proposed in this paper for…
