Abstract:Converter is a typical switching system for the action of the power switch. It includes two dynamical states of the continuous and the discrete. The conventional method of modeling was based on the linear system theory, through the methods of averaging, coordinate transformation and linearization etc, an approximate model could be obtained. Considering the hybrid trait of the converter, this paper deduces the switching system model of the converter, and gives the switch sequences respectively for the inverter and the rectifier. The new model is accurate, and it can represent the actual system completely. By introducing the determinant principle of stability for the linear switch system, this paper analyzes the switch course stability of the converter. The final simulation results has good agreement with the theory analysis. The validity of the method presented in this paper is approved.
