Abstract: The present discloses a linear time-periodic model of a three-level inverter considering neutral point dynamics. In the present application, a piecewise linearization processing method is adopted to divide non-differentiable terms in an original nonlinear model of a three-level inverter into a plurality of linear segments, and linearization processing is carried out in each segment to eliminate the non-differentiable terms of a non-differentiable part (such as a neutral point voltage and a neutral point current) and ensure that the linear time-periodic model of a three-level inverter obtained is locally analyzable, which avoids the problem of difficulty in overall linearization. The linear time-periodic model of a three-level inverter is generated by combining with a steady-state trajectory, which can comprehensively reflect small signal characteristics of a three-level inverter. This model can be applied to small-signal stability analysis of power systems containing a three-level inverter.
