SEQUEL: A Public-domain Simulation Platform for Electronics and Power Electronics

SEQUEL (a Solver of circuit EQuations with User-defined ELements) is a public-domain simulation package that has been used for a variety of applications. A graphics interface has recently been added to SEQUEL, in order to make it more user-friendly and better suitable for teaching purposes. The package can be downloaded freely. In this paper, some of the features of SEQUEL are described, along with examples.
