Total IGBT/FWD Cell Losses vs Output Current
The table and charts below can be used for estimating IGBT losses as a function of cell output current. Primary
source values are used. Losses include conduction and switching losses for both the IGBT and FWD. Losses shown
are per cell. Individual IGBT/FWD losses are ¼ that of shown (40-140A) and 1/8 that of shown (200-260A).
* The data above assumes 0.85 motor power factor, 0.95 motor efficiency, 105% modulation, 600Hz switching
frequency, 60Hz output frequency, Eupec IGBTs, and a 1015VDC bus.
Alternatively, total cell IGBT/FWD losses can be estimated as follows:
40/70Acell:
Pigbt = 0.02828 x Iout ^2 + 3.23561 x Iout + 0.39
100A cell:
Pigbt = 0.01908 x Iout ^2 + 3.55781 x Iout + 0.07857
140A cell:
Pigbt = 0.01326 x Iout ^2 + 2.758 x Iout + 0.14545
200A cell:
Pigbt = 0.00682 x Iout ^2 + 2.59283 x Iout + 0.11734
260A cell:
Pigbt = 0.0045 x Iout ^2 + 2.99225 x Iout + 0.04933
For individual 40-140A IGBT/FWD individual module losses, divide PigbtFWD by 4.
For individual 200-260A IGBT/FWD individual module losses, divide PigbtFWD by 8.
