Abstract Traditional switch function model for power electronics circuits only describes the control changes of circuits rather than their conditional changes,which may cause a loss of their dynamic information.Considering this fact,this paper establishes a mixed logic dynamic (MLD) model for power electronic circuits as a predictive model.Based on it,the optimal solution will be replaced by the feasibility solution which,together with the move blocking principle,will be applied to the circuit model predictive control (MPC) so as to effectively reduce the total number of control sequence and the switch frequency,and realize the fast solution of circuits,which offers a solution to the hard problem of calculating circuit MPC.The paper elaborates the algorithm and realization procedure of the control sequence of power electronic circuits and verifies the feasibility and validity of the algorithm by the three-phase inverter circuit.

Key words： Model predictive control mixed logic dynamic model inverter feasibility move blocking
