Calculation example
a. The maximum junction temperature shall be
calculated for a module IXBOD 1 -30R at an
ambient temperature Ta = 60 °C, an exponentially
decaying current ITM = 40A, a pulsewidth tp = 2 µs,
an operating frequency f = 50 Hz and natural
convection. From the diagram Fig. 6 the energy per
pulse is obtained:
Ep1 = 6 x 10-3 Ws
For a module IXBOD1-30R the number of single
IXBOD elements is:
n=3
At natural air cooling the thermal resistance junction
to ambient amounts to (Fig.8):
RthJA = 20K/W
and the unknown temperature can be calculated as:
TVJmax1 = Ta + n • f • Ep • RthJA + Kp • Ep
TVJmax1 = 60 + 18 + 4.2 = 82.2°C
b. If following these steady-state conditions an
overload for 1 minute occurs with ITM= 60 A and a
pulse-width tp = 4 µs at the same operating
frequency f = 50 Hz, then the resulting maximum
junction temperature is calculating as follows:
TVJmax2 = TVJmax1 + (Ep2-Ep1) • n • f •ZthJA(t) + Kp • (Ep2-Ep1)
The diagrams Fig. 11 and Fig. 8 show
Ep2= 14x10-3 Ws
ZthJA(t = 1min) = 12K/W
From what follows:
TVJmax2 = 82.2 + 14.4 + 5,6 = 102.2 °C
which is allowed because the maximum admissible
junction temperature TVJM = 125 °C.
