摘要：
If parameters of three-phase inverters in parallel are different, there will be circulation current between the parallel inverters. Circulation current leads to the increase of energy loss, reduction of efficiency, and distortion of the inverter output voltage and current waveform. This paper researches the improved circulation current control strategy and load sharing control strategy to suppress the circulation current based on space vector pulse width modulation (SVPWM) algorithm. The control strategies not only have good performance on suppressing circulation current and load sharing, but also significantly improve quality of output voltage and current of inverters. The strategies are verified by simulation.
