IGBT switching energy

What datasheet?

Any power IGBT ds give you Eon and Eoff as function of the current. Like this, page 4 :

"W>> I'm trying to evaluate switching losses for an igbt with a 10uH load...

The test circuit inductance is chosen to allow testing at a reasonably low duty cycle without a lot of ripple in the current of the DUT.

It has no effect on switching losses if turn-on and turn-off currents are duplicated, at the voltage specified, in each instance.

In real life, lower inductance suggests higher peak current at turn-off, for the same average collector current - aggravating losses occuring in the current tail portion of the waveform. Adjust your loss calculations accordingly.
