i want to know how to drive this IGBT IHW20N120R3 https://www.ges.cz/sheets/i/ihw20n120r3.pdf ??
also i want to know how to calculate the power dissipation ( heating losses ) when it works with 20A and 5 A,
when it is driven by a PWM signal (18A, 220V) and a duty cycle of 1/4, the nominal current is 5A.
Those plots are of switching energy loss, so find your total switching loss per PWM period and multiply that by your PWM frequency to get switching power losses.
