Sažetak
Computer simulations are very important in the analysis and design of power electronic converters and systems. In this article an approach of modelling DC/DC converters with circuit oriented simulation programs is discussed. This approach is chosen instead of use of special-purpose programs that manipulate state space equations, because on that way the focus remains on the circuit rather than on the mathematics of the solution. Circuit models of the boost DC/DC converter are presented. Following those approaches, circuit models for other basic converters, such as buck and buck-boost, can be easily derived. These circuit models are called adaptive models because they can recognise an appropriate mode of operation of the DC/DC converter (CCM-continuous conduction mode or DCM-discontinuous conduction mode). The advantage of the adaptive model is also that it can be used in AC analysis. Modern circuit oriented simulation programs (PSpice, SIMPLORER) can linearize such circuit models around the steady-state operating point and on that way enable successful AC analysis without need for deriving analytical expressions.
