摘要：

The paper presents a new computer simulation program Simplorer 4.1. This is a high performance simulation tool allowing the user quick and easy simulation of complicate technical systems in a variety of application areas, in particular in power electronics. A simulation tool and a practical analysis procedure are described consequently. For creating a precise simulation model Simplorer offers two different methods, modelling with a text editor in the SML language and modelling with a graphical input tool Schematic. Building the simulation model with the text editor requires some experience, on the other hand graphical tool is more user friendly orientated. In either case, a good overview over the employed libraries is required. In a separate library we can find Semikrons models of diodes and IGBT transistors. Their electrical characteristics are defined with measurements on real Semikron semiconductor elements. This attribute assures objectivity of simulation results and also gives Simplorer priority in computer simulation in the area of power electronics. The simulation model is further analyzed by the Simulator containing different simulating procedures (TR, AC, DC). The quality and objectivity of the simulation result depend on the simulation parameters. They are defined with regard to the components used in the simulating model and required accuracy. In the final sequence, data evaluation takes place. Simplorer contains two data postprocessors DAY and DAY Optim. They offer many mathematical and graphical research options and also the creation of the final presentation of the entire problem analysis. Simplorer also contains an Experiment Tool that repeats the simulation and through build-in task types and user defined changeable parameters provides the optimal solution of simulated problem. At the end of the paper the practical use of Simplorer is briefly demonstrated, dealing with single-phase inverter with Semikron switching modules. To take full advantage of the Simplorer's performance, its essential details and properties should be well known.
