Simtel Power Electronics is interactive learning and simulation software, a very powerful tool to understand core concept of the subject. Power electronics is the combination of the Power, Electronics and Control. Power electronics system work as an application of solid-state electronics for the control and conversion of electric power. With the help of SimTEL Power Electronics we have tried to develop a teaching tool which covers all topics of the subject, explained virtually through high quality simulation, rich theoretical content and attractive animated diagrams.
