Abstract
Provided is a method for suppressing common-mode current of neutral line in T-type three-level three-phase inverter, the method of the present disclosure can effectively suppress LC filter resonance contained in the currents of a circulation neutral line and inversion side of a inverter, reduce the common-mode leakage current of the inverter, and improve the performance of the inverter.
