In LTspice, design your circuit elements to realize steady-state Vds(ott) = 400 V, lacon) = 50 A, Vision) = 20 V, Rş(ext) = 20 ohm, Tcase = 25 °C, fsw = 10 kHz, duty = 0.5. 1) Plot Vas, Vds, ls on one plot showing a turn-on transient moment (zoom in as much as possible). Note that to plot a differential voltage in LTspice (e.g., Vab), you may need to plot V:-Vo with V. and Vo referencing to ground. Since here Vas is much smaller compared to Ves, you may want to plot V2*10 to show its behavior more clearly. 2) Plot Ves, Vas, la on one plot showing one switching period (i.e., both turn on and turn off). 3) Plot the turn-on switching loss by calculating Vos*la. 4) Plot Vos*lover a switching period and use the software to calculate the combined switching and conduction losses.
