Abstract

Three types of models in virtual electrical experiment, circuit structural model, circuit computation model, and human–machine interaction model, are studied. The XML-based circuit structural model describes a circuit’s structure by marking the composing components, which makes the model well formed and extensible. Computation model is constructed based on the circuit topology structure and electrical principles (KCL and KVL), and an algorithm of generating computation model is proposed. Interaction model is designed to describe the interaction information in the operation of the virtual experiment. The models are valuable in design and development of virtual electrical experiment.
