"Lauritzen and Ma" Soft Recovery Model Waveforms

Four (4) Critical Parameters:

  1. a: di/dt (large negative number)
  2. T1: Time during "a" slope (ns)
  3. IRM: Peak negative current (positive number)
  4. trr: Time constant during tb time interval (ns)

This model is based on the model published by Peter Lauritzen and Clifford Ma in the IEEE Transaction on Power Electronics, Vol. 6, No. 2, April 1991, pp. 188 – 191.
