| Abstract: | This paper sets up a double control configuration based on symmetrical components and bisynchronous coordinates.The outside voltage loop and the inside current loop both adopt feedforward decoupling control,thus the three-phase four-leg inverter has the ability to supply unbalanced loads.A 1.5 kW three-phase four-leg inverter has been built and the experiment results validate the operating principle. |
