초록
This paper introduces a low-frequency switching method for the neutral line of TNPC inverters to achieve high efficiency. By applying the method, the switching loss in the neutral line is reduced. In order to compensate the current distortion near zero-crossing points, the partial switching strategy is applied. Both the simulation and the experimental results verify the usefulness of the proposed method.
