Abstract :
To guarantee symmetric output voltage with asymmetric load for three-phase inverter, a feedback linearization based on inverse system for three-phase inverter is proposed, which can improve system adaptability and stability under complex load conditions and disturbances. A prototype consisting of 1kW three-phase inverter with asymmetric load based on feedback linearization via dq0-axis transformation is built. The simulation and experimental results demonstrate the validity of proposed scheme.
