4.2.7 Switching Loss vs. Collector Current
Figure 12 shows the power loss dependency upon collector current during IGBT module turn-ON and
turn-OFF. The information in this figure can be used for calculation of switching loss, that is, per single pulse
at the inductive load switching circuit. So, loss can be calculated in terms of switching frequency.

4.2.8 Switching Loss vs. Gate Resistance
Figure 13 shows the power loss dependency upon R
G
during IGBT turn-ON and turn-OFF.
(Refer also to section 4.2.7).
