| Abstract: | A control method for decoupling positive negative and zero sequence components used in three-phase four-leg inverter control system is proposed by rotating coordinate transformation, the unbalance of output voltage of three-phase unbalanced load can be decreased by the novel method, and the 3DSVPWM wave generation mode is simplified, which is more conducive to engineering implementation. The simulation and experimental results are demonstrated to verify the validity of the novel method. |
