Innovation and improvement of electronic devices have been throughout the years a massive boost for electronic sciences, no matter what kind, and power electronics is not an exception. Industry and research still aim at creating devices able to tackle old and new challenges with increasing performance, allowing designers to obtain better and better results in terms, just to give some examples, of power density, speed and efficiency. One of the final parts of the production process consists in testing prototyped devices and measuring their characteristics, allowing to asses if quality and performance standards have been met and competitiveness on the market is likely to be achieved, as well as to collect data which will be reported on datasheets.
