- Abstract
Traditional three - leg inverter can output three - phase symmetrical voltage in the case of three - phase symmetrical load. But it is difficult to output three - phase symmetrical voltage when the three - phase load is asymmetric. This new inverter can effectively suppress the unbalanced load current to voltage disturbances under the unbalanced load, to ensure approximately symmetrical three - phase voltage output. The control method adopts the new type of three - dimensional space vector pulse width modulation (3D - SVPWM), and the coordinate transformation of CLARK PARK closed - loop control. Through the simulation of MATLAB, it is verified that the three - phase four - leg can solve three phase output voltage problems when the three - phase load is asymmetric. [ABSTRACT FROM AUTHOR]
