Performance of power semiconductor devices and the impact on system level

Inhalt:
The performance of power modules is based on both the internal configuration, i.e. layout and used semiconductors, and the external operating conditions including the cooling concept. This mutual interaction between power module and application is investigated to provide a guideline for configuring appropriate power modules and building of optimized systems. Using present diode technologies and operating conditions for a given switch, a relation is established towards achievable power density, switching frequency, and power-cycling capability. Based on these findings, a decision strategy on system level is provided, and recommendations for the use and operation of different diode types are given.
