Fig. 9 Preferred circuit for paralleled IGBT’s
current sharing without any external auxiliary element.
After all some care must be considered to reach an
optimized circuit and to obtain the total performance of
the IGBT (Fig. 9). The IGBTs must have independent
values of R
well as an auxiliary collector resistor R
used.
The external resistors R
mounted on an additional circuit board near the paralleled
modules, and the R
changed to zero ohms.
The R
compensate the wiring resistance in the auxiliary emitters
what could make the emitter voltage against ground
unbalanced.
The R
create an average value of V
for V
The Mechanical assembly of the power circuit must be
symmetrical and low inductive.
The maximum recommended gate charge is 9,6 C.
See als Fig.14.
