Frequently Asked Questions
Is there any company involved in the iPES project?
No. It is a project powered by the Power Electronic Systems Laboratory (PES) at the ETH Zurich.
Is it possible to use iPES for education in industrial companies?
Yes. iPES is free, for non-commercial use, including training lectures in companies.
iPES will be available also in future, simply because we want to support education in
power electronics and we want people to use it.
What are the differences between iPES and circuit simulators (like PSpice) in education?
Basically, while circuit simulation is done in addition to the practical exercises in the
laboratory for speeding up prototype development, iPES is used in addition to textbooks in the
theoretical part of the course and does speed up understanding of the theory of a circuit.
Will there be more translations?
Yes, Portoguese, Thai and French will be among the next translations.
We are very open for comments and ideas.
What is the simulation engine used inside the applets?
It is self-written in order to minimize the size of the files (applets) to be downloaded and to
optimize the simulation speed. This is necessary to make iPES available also to users with
slow modem-connections and low clock frequency computers.
How long does it typically take to produce one new applet?
Just a few days. But all work is based on a specially designed library which has been developed over
more than one year and which is improved continuously.
How often are there updates?
We continuously improve older applets of iPES and add new material. Minor changes and additions will be done every
2 or 3 weeks. The download-version will be updated every 5 or 6 months.
