Forward recovery energyE
Energy generated inside the diode during the diode turn-on. Due to the fast
turn-on behaviour of modern freewheeling diodes for IGBTs the turn-on energy
of the diode is no longer specified as its portion of the total losses is negligible

Timeperiod todetermine the turn-off energy
When determining the losses metrologically, the measuring delay time on
capturing the currents must be considered. They occur with the use of Rogowski coils
amongst others. Themeasuring delay times have tobe compensatedaccordingly.
