| Abstract |
Computer-aided simulation is essential in today’s power electronics. This implies the need for wellimplemented
device models. Because of their specific structures, the power devices exhibit a different
behaviour as compared to the low-power ones. Therefore, special device models are developed,
ranging from purely behavioural to physical, the latter being most accurate. However, many popular
circuit simulators still use only behavioural equivalent circuit models, making the recent advances in
the modelling domain unavailable to a large number of users.
In the paper, a free simulation package based on the Berkeley SPICE3f5 is presented [1]. The original
simulator code has been modified as to include a modern physics-based PIN diode model. This proves
that modern power device models may be supported by popular circuit simulation environments. In
order to make the software along with the model widely available, a web-based user interface has been
developed. Several features are emphasized that make the package particularly well-suited for
educational purposes. |
