In high-quality education, topics concerning the behavior and control of electrical machines and power electronics have to be taught not only theoretically but also in a practical manner. Hard-and software tools are necessary to fulfil this obligation. Nevertheless, commercial systems partially lack of functionality or full accessibility to implement custom solutions, which is obligatory in the research and education domain. Therefore, a digital signal processing system is presented, that allows full modification of every used device, both in hardware and in software.
