Abstract：The power weighting distribution of three-phase parallel inverter system can be realized only by adding weighting circuits or virtual impedances. In this paper, based on single inverter with feedback linearization control, the parallel inverter system is able to achieve power weighting distribution accurately in dq0 coordinate without the additional circuits or virtual impedances. Through inverse system method of nonlinear control, the feedback linearization control for three-phase three-wire inverter with the consideration of dead-time effect is illustrated. Moreover, the possibility of power weighting distribution for three-phase parallel inverters in dq0 coordinate is further discussed. The experimental results demonstrate that the proposed control strategy can guarantee the steady state precision of power weighting distribution. In addition, the dynamic characteristics can be improved.
