How much is the loss erro introduced for not considering the diode reverse recovery behavior in the thermal simulation?

Question

Hello everybody,

I’m working with a thermal library and loss calculation. I add the diode thermal model, but I don’t know if the reverse recovery behavior is considered with the thermal model in Plecs? If not, How much is the loss erro introduced for not considering the diode reverse recovery behavior in the thermal simulation? How do I do that?

Thank you in advance,

Wilmar

Answer 1

it depend strongly from the diode you use, power diode have different effect depending from the temperature, for "normal" diode the temperature variation of the reverse recovery is also a factor 100%.

But I think this will not be the main cause of efficiency degradation in your power train, that means in first approximation is negligible.
