Abstract :
A new control scheme featuring a combination of state-feedback-with-integral control and repetitive control is proposed for UPS inverters. A state observer is also embedded to predict output voltage and capacitor current needed by the state-feedback controller, based on the sensed values of output voltage and load current. The system exhibits high-dynamic response and near-perfect output voltage waveform
