Description

Ideal Diode with reverse recovery effet

The reverse recovery effect is modeled using a Voltage Controlled Current Source as shown in the figure below.

Internal parameters of the model are calculated using the following equations:

$\tfrac{L_{rr}}{R_{rr}} = \tfrac{1}{\ln 10} * [t_{rr} - I_{rrm} / (\tfrac{dI_r}{dt})]$

$K = \tfrac{I_{rrm}}{L} * (\tfrac{dI_r}{dt})^{-1} * [1 - \exp(\tfrac{-I_{rrm}}{L * \tfrac{dI_r}{dt} * (K+1/R_{rr})})]^{-1}$

If Irrm and trr are provided (> 0.0), Qrr is ignored. If Irrm or trr is equal to 0.0, its value is derived from the following equations:

$(\tfrac{1}{2} - \tfrac{1}{\ln 10}) * (\tfrac{dI_r}{dt})^{-1} * I^2_{rrm} + \tfrac{t_{rr}}{\ln 10} * I_{rrm} - Q_{rr} = 0$

Irrm value is also checked to validate the geometric law:

$I_{rrm} < t_{rr} * \tfrac{dI_r}{dt}$
