Explain Static and dynamic characteristics of switching devices... | Filo

A power IGBT switches a 600  V, 25  A inductive load at 100 kHz with a 50 per cent on-time duty cycle. Turn-on and turn-off both occur in 100  ns and the collector on-state voltage is to be 2  V. Calculate the total power losses, Pd, of the switch. The switch has a thermal resistance Rθj-t h s=0.05  K / W, and the water-cooled heatsink provides a thermal resistance Rffts -w=0.05  K / W. Calculate the operating junction temperature if the water for cooling is maintained at 35^∘ C. The 25  A stead
