Power losses and dissipation
Doc ID 022726 Rev 2
43/60
Both forward characteristics are temperature dependent, and so must be considered under
a specified temperature.
The linear approximations can be translated for IGBT in the following equation:
Equation 15
and, for freewheeling diode:
Equation 16
The conduction losses of IGBT and diode can be derived as the time integral of the product
of conduction current and voltage across the devices, as follows:
Equation 17
Equation 18
where T is the fundamental period.
The different utilization mode of the SLLIMM-nano, modulation technique, and working
conditions make the power losses very difficult to estimate, it is therefore necessary to fix
some starting points.
