Question

lem 3): [1S PT] For the clamped inductive circuit shown in the figure below, vá and lo 4A. The data sheets of a switching device specify the following t corresponding to the linearized characteristics fot clamped-inductive switching =50ns Iri-100 ns trv = 100ns 75 ns50 ns t 200 ns D I6 PI Draw switching signal the voltage across the switch and curent through the switching power losses 2) 19 PT] Calculate the turning on and turning off time of the traisistor. Calculate the energy swiching power losses for the turning on and turning off of the switch separately at frequency of 10 kHZ and 20 kHZ. What is the effect of increasing the switching frequency on the power losses of the transistor the swi VT
