Inhalt:
This work presents the challenges of paralleling 3300 V Silicon carbide MOSFET power modules. Based on a static device characterization, the static current derating depending on conduction variation and parallel number of modules is calculated. Furthermore, an investigation on dynamic imbalance of switching losses due to device parameter variation is realized based on a parametrized simulation model. Finally, a comparison of three different approaches of external module gate loop designs is presented to find the best solution.
