HW-3(c)

Hi, all. For Q3(c), do you think it is assumed that Ds has the same I-V characteristics as D or not? Because if Ds is identical to D, then when D is on, Ds will shunt approximately the same amount of current as D. In that case, when Ms is on, the reverse recovery loss of Ds will be inevitable.

You can assume that diode characteristics are such that D conducts the inductor current while Ds current is zero at the time before Ms turns on
