I want to find the turn-on losses of this device (NVH4L018N0755C1) in a buck converter. I am operating the converter with some minimum negative current (from -1A to - 20 A). Theoretically, I expect that this negative current will flow through the body diode briefly, and then, the MOSFET would turn on. However, the turn-on losses of the device are predicted to be 0 W by the thermal model.
Analysing the thermal model in the image attached, there is no turn-on loss information below 0 A. Also, the equation only calculates the turn-on loss when (i > 0).
What modifications can I make to this model to estimate the turn-on losses when there is a negative current? Can I copy the tabular information for the positive current and use it for the negative current? eg: If at 40 A, the Energy is 3.4 uJ can I make it -40 A, E = -3.4 uJ?
