This paper presented a virtual oscillator based control for parallel connected inverters with adaptive characteristic. This control method made inverters equivalent performances as a RLC resonance circuit parallel with an adaptive module, which had dual nature with controlled current source and controlled linear resistance. In virtual oscillator, the value of adaptive module could be controlled by terminal voltage and output current, made outputs of the models in parallel system could be synchronous operation, reduce circular current gradually. By this mean, three single-phase inverters for the same capacity parallel operation was realized. And it could maintain the amplitude and frequency of terminal voltage when load changed, make output voltage characteristics of parallel system controlled by this method harder. The feasibility of control method was confirmed by Matlab/Simulink.
