[Abstract]:In view of the current power electronic simulation software, the simulation of electromagnetic transient process of power switch device is not accurate enough, and the strong rigidity circuit causes numerical simulation calculation divergence and so on. A discrete state event driven (DSED) simulation analysis method based on quantized state system (QSS) is proposed. This method needs to add automatic identification of power electronic system switching process and automatically write the state equation according to the circuit topology and the state of the relevant algorithm. A state equation and output equation extraction and analysis method based on graph theory is proposed. First of all, through theoretical analysis, the standard form of state equation can be obtained by inserting the selected device model into the circuit, and then, the method of parameter structure matrix programming of power electronic system circuit is proposed. Based on this method, a correlation analysis is carried out to analyze the need to relist the state equations for each switch in a switching circuit. Finally, several typical power electronic system circuits are simulated and calculated, and the results show that the proposed method is effective.
