Guide Overview

In modern societies, a substantial amount of electrical energy is required to operate electronic circuits or controlled electrical drives. The requirement to supply electrical energy to these applications is met through the use of power electronic converters. Power semiconductors (IGBT or MOSFET) are controlled devices which are used to realize these converters. Even though the semiconductor industry has made significant progress in the development of powerful and efficient components, power losses still occur in these components and cause them to heat up.

This step-by-step guide describes the basic concept of double pulse testing (DPT) and the necessary measurement setup and provides an overview of the parameters influencing the measurement. Furthermore, practical tips for carrying out the measurements are presented.
