Switching losses:
1. P = f * (Eon + Eoff) --> P = 32000 Hz * (383 uJ + 293uJ) = 21,632 W
2. Pswon = 0,5 * Un * In * Füein * tr/T --> P = 0,5 * 325 V * 8,88 A * 1,2 * 14,6 ns / (1/32000 Hz) = 0,809 W
Pswoff = 0,5 * Un * In * Füein * tr/T --> P = 0,5 * 325 V * 8,88 A * 1,4 * 23 ns / (1/32000 Hz) = 1,487 W
Found this formula on www.mikrocontroller.net/articles/IGBT#Stromtragf.C3.A4higkeit
So it's a very big differnce. Does anyone know how to do it correctly to get a better understaning of the losses.
ON-Losses:
Pon = Vcesat * In * ton / T = 1,55 V * 8,88 A * 0,5 = 6,88 W
ton= 50%
Can I do it like this? Thank you for your answers.
