4. Qrr - Area under curve defined by t rr
and IRRM
5. di (rec) M / dt - Peak rate of change of
current during t b portion of t rr
1. diF/dt - Rate of change of current through zero
crossing
2. IRRM - Peak reverse recovery current
3. trr - Reverse recovery time measured from zero
crossing point of negative going IF to
point
where
a line passing through 0.75 IRRM
and 0.50 IRRM
extrapolated to zero
current
Q rr =
