Abstract:
Magnetic coupling effects have to be considered for neighboring inductive parasitics and overlapping commutation loops, and become more pronounced for transients with high current slopes. This paper shows the influence of coupling effects on the short circuit transients of semiconductor switches. Utilizing a special adapter, different coupling magnitudes, orientations, and origins could be displayed. Depending on the coupling, a softer or more dangerous short-circuit dynamic could be the consequence. Measures against coupling effects are summarized.
