Abstract: The paper describes the mathematical model of the buck–boost converter, capable of operating as a buck-, and a boost- converter, on the basis of a numeric-analytical method of mathematical modelling of dynamics of semiconductor converters. We received the dependences of the output voltage and the current through a power inductor on load. The received mathematical model can be applied to the research of the converter behaviour.

Keywords: mathematical modelling, combined converter, switching function
