Widespread application of IGBTs
in the past two decades has resulted in dramatic improvement in performance of
power electronic converters, the efficiency of these devices has made its mark,
reducing the cost of power electronic systems and improving their own
reliability, making them the first option of the manufacturing industry,
Paralleling systems for IGBTS and diodes is one of the best alternatives to
achieve a best performance.
The conclusion is that
paralleling systems for igbts provides an advantage due to the improved thermal
behavior of several small chips rather than fewer big ones. The breakthrough in
performance is seen when real life data of parameter variations within one
power module are considered, instead of the datasheet values, which suggest a
much higher spread than actually seen in real life.
